[IDE/Editor] Show HN: A code editor that integrates into the browser When the startup I was working for shut down, I knew it would probably be a while before my health allowed me to commit to a new role, so I decided to start working on some personal projects to keep my mind active and engaged.<p>With AI-augmented VS Code forks being all the rage at the time, I wanted to take a slightly different angle on a code editor&#x2F;viewer using the same core technology. That led me to building Tachi Code, a Monaco-based code editor that integrates directly into your browser as an extension to streamline your more ephemeral coding tasks, so you can spend less time switching between your code editor and browser.<p>The original flow that piqued my interest was viewing raw source files or API responses. Historically, I&#x27;ve used a JSON formatter extension to prettify JSON, but I wanted something more powerful, more universal, and quite frankly, something that looked better, so I built Tachi Code with the ability to detect when you&#x27;re viewing pre-formatted text and inject itself into the page, so it&#x27;s always beautifully syntax highlighted, foldable, and regex searchable. Then I added context menu integrations, so you could quickly edit snippets, compare text, or view the current page&#x27;s source in Tachi Code&#x27;s editor.<p>The browser extension works offline with the only external HTTP requests going to GitHub to retrieve JSON Schemas or additional themes. All user data stays local. The only tracking is CloudFlare&#x27;s web analytics beacon on TachiCode.dev (not present in the browser extension or in the EU).<p>TachiCode.dev is a sandbox environment that serves the latest commit of Tachi Code&#x27;s editor hosted on CloudFlare Pages.<p>The core stack is: - React 19 - Monaco Editor - Radix UI - Zustand - Shiki - WXT (full SBOM is available via the about dialog if you want to dig deeper)<p>Monaco Editor provides the code and diff editors, as well as low level systems for configuration and theming. There&#x27;s a lot of hackery involved in surfacing those systems and integrating them into the larger React app. Shiki is used to provide more complete syntax highlighting than Monaco Editor provides out of the box. The rest of the UI is primarily based on Radix UI components, typically starting from a shadcn template and then reworked to use colors provided by the theme system. Zustand is my go-to for any kind of shared&#x2F;persistent state. WXT just turns browser extension development and publishing into a breeze.<p>If you&#x27;ve got any feedback or a question about how the app was developed, I&#x27;d love to hear it!

[Other] Show HN: Nia – MCP server that gives more docs and repos to coding agents Hi HN, I’m Arlan, and I built Nia (<a href="https:&#x2F;&#x2F;www.trynia.ai" rel="nofollow">https:&#x2F;&#x2F;www.trynia.ai</a>), an open MCP that integrates with coding agents like Cursor, Continue, and Cline so they can retrieve external knowledge better than current approaches.<p>Coding agents generate code well but lose accuracy when the answer lives outside the repo in front of them. Developers end up pasting GitHub links, docs, and blog posts by hand and hoping the agent scrolls far enough. Long context windows help, but recent “context rot” measurements show quality still drops as prompts grow. For example, in LongMemEval, all models scored much higher on focused (short, relevant) prompts (~300 tokens) than on full (irrelevant, 113k tokens) prompts, with performance gaps persisting even in the latest models (<a href="https:&#x2F;&#x2F;research.trychroma.com&#x2F;context-rot" rel="nofollow">https:&#x2F;&#x2F;research.trychroma.com&#x2F;context-rot</a>).<p>Nia is a MCP that gives more context to any coding agent or IDE. It Indexes multiple repos and docs sites and makes this available via MCP to your coding agent so it has much more context to work with, giving you more specific and accurate answers.<p>Nia uses a hybrid code search architecture that combines graph-based structural reasoning with vector-based understanding. When a repo or documentation is ingested, Tree-sitter parses it into ASTs across 50+ languages and natural languages, and the code is chunked by function&#x2F;class boundaries into stable, content-addressable units. These chunks are stored both in a graph db to model relationships like function calls and class inheritance, and in a vector store. At query time, a lightweight agent with give_weight tool dynamically assigns weights between graph and vector search based on intent (e.g., &quot;who calls X&quot; vs &quot;how does auth work&quot;), and both paths are searched in parallel. Results are fused, enriched with full code context, and passed through multi-stage rerankers: semantic reranker, cross-encoders, LLM-based validators.<p>Early Signal: In internal evals we improved Cursor’s performance by 27 % once Nia had indexed external docs models couldn’t get from their training data or searching the web.<p>Quickstart: &lt;<a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=5019k3Bi8Wo" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=5019k3Bi8Wo</a>&gt; Demo: &lt;<a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Y-cLJ4N-GDQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Y-cLJ4N-GDQ</a>&gt;<p>To try it out: grab an API key at <a href="https:&#x2F;&#x2F;app.trynia.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;app.trynia.ai&#x2F;</a> and follow instructions at <a href="https:&#x2F;&#x2F;docs.trynia.ai&#x2F;integrations&#x2F;nia-mcp" rel="nofollow">https:&#x2F;&#x2F;docs.trynia.ai&#x2F;integrations&#x2F;nia-mcp</a>.<p>Try it and break it!

[Monitoring/Observability] Show HN: TheProtector – Linux Bash script for the paranoid admin on a budget Hi HN,<p>I spent the past year building this in my spare time because I got tired of enterprise security tools that cost $50K&#x2F;year and don&#x27;t understand Linux.<p>TheProtector is a comprehensive security monitoring tool that actually runs on the systems we use (Linux) instead of being a Windows-first afterthought. Built it entirely on a $500 laptop because I believe good security shouldn&#x27;t require unlimited budgets.<p>Features: - Real-time process, network, and file monitoring - YARA malware detection with custom rules - eBPF kernel monitoring (when available) - Behavioral baseline establishment and anomaly detection - Active threat response (blocks IPs, kills processes, quarantines files) - Anti-evasion detection for rootkits and advanced threats - Honeypots for attack detection - Web dashboard for monitoring - Single bash script, no complex installation<p>The tagline is &quot;not perfect but better than most&quot; because I&#x27;m tired of security vendors claiming their tools are flawless. This actually works, costs $0, and you can read every line of code.<p>I know bash isn&#x27;t the sexy choice for security tools, but it runs everywhere, has zero dependencies, and most Linux admins can read&#x2F;modify it. Sometimes boring technology that works is better than fancy technology that doesn&#x27;t.<p>It&#x27;s designed for the intersection of &quot;paranoid about security&quot; and &quot;don&#x27;t have enterprise budgets&quot; - which describes most of us actually running Linux systems.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;IHATEGIVINGAUSERNAME&#x2F;theProtector">https:&#x2F;&#x2F;github.com&#x2F;IHATEGIVINGAUSERNAME&#x2F;theProtector</a><p>Been running it on my own systems for months. Catches the stuff that matters and doesn&#x27;t flood you with false positives. If you hate expensive security theater as much as I do, might be worth a look.<p>Open to feedback, especially from folks who know more about this stuff than I do.<p>Thanks, IHATEGIVINGAUSERNAME (yes, I really do hate giving usernames)

[Other] Show HN: The missing link of a bookstore's tech stack Hi HN!<p>I built Bookhead because I used to work as a bookseller and I wasn&#x27;t happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick &amp; mortar). So I decided to make my own bookselling app...a classic hacker distraction.<p>Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand<p>I have a very exciting roadmap that I&#x27;m not ready to fully reveal, but it&#x27;s all based on books. I&#x27;m building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I&#x27;m hoping to change that. I have a blog post that lays out my vision here: <a href="https:&#x2F;&#x2F;bookhead.net&#x2F;blog&#x2F;fragmented&#x2F;" rel="nofollow">https:&#x2F;&#x2F;bookhead.net&#x2F;blog&#x2F;fragmented&#x2F;</a><p>The current iteration is like &quot;data engineering as a service for books.&quot; A book is a powerful thing. I&#x27;m hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It&#x27;s a crowded market but I&#x27;ve had fun making the bookselling app that I believe should exist.<p>If you know any booksellers, please let them know about this! I&#x27;m onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It&#x27;s frustrating to wait for two weeks for a point of sale provider to setup an integration. It&#x27;s almost like they don&#x27;t care about their customers. Some providers even require ethernet cables for their software...still partying like it&#x27;s 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation.<p>I&#x27;m currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can&#x27;t focus on this project like I need to. I&#x27;ve gotten good validation from booksellers and other technically savvy folks in the industry (I&#x27;ve heard from two different companies that they&#x27;ve considered building something like this), so I believe I have something valuable. I&#x27;m not interested in funding from somebody who doesn&#x27;t share my love for books or doesn&#x27;t support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive.<p>Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit.

Would love to hear what you think!

[Other] Show HN: Go Command-streaming lib for distributed systems (3x faster than gRPC) I created cmd-stream-go, a high-performance client-server library based on the Command Pattern, where Commands are first-class citizens.<p>Why build around Commands? As serializable objects, they can be sent over the network and persisted. They also provide a clean way to model distributed transactions through composition, and naturally support features like Undo and Redo. These qualities make them a great fit for implementing consistency patterns like Saga in distributed systems.<p>On the performance side, sending a Command involves minimal overhead — only its type and data need to be transmitted. In benchmarks focused on raw throughput (measured using 1, 2, 4, 8, and 16 clients in a simple request&#x2F;response scenario), <i>cmd-stream&#x2F;MUS</i> (<i>cmd-stream&#x2F;Protobuf</i>) is about 3x (2.8x) faster than <i>gRPC&#x2F;Protobuf</i>, where <i>MUS</i> is a serialization format optimized for low byte usage. This kind of speedup can make a real difference in high-throughput systems or when you&#x27;re trying to squeeze more out of limited resources.<p>By putting Commands at the transport layer, cmd-stream-go avoids the extra complexity of layering Command logic on top of generic RPC or REST.<p>The trade-offs: it’s currently Go-only and maintained by a single developer.<p>If you’re curious to explore more, you can check out the cmd-stream-go repository (<a href="https:&#x2F;&#x2F;github.com&#x2F;cmd-stream&#x2F;cmd-stream-go">https:&#x2F;&#x2F;github.com&#x2F;cmd-stream&#x2F;cmd-stream-go</a>), see performance benchmarks (<a href="https:&#x2F;&#x2F;github.com&#x2F;ymz-ncnk&#x2F;go-client-server-benchmarks">https:&#x2F;&#x2F;github.com&#x2F;ymz-ncnk&#x2F;go-client-server-benchmarks</a>), or read the series of posts on Command Pattern and how it can be applied over the network (<a href="https:&#x2F;&#x2F;medium.com&#x2F;p&#x2F;f9e53442c85d" rel="nofollow">https:&#x2F;&#x2F;medium.com&#x2F;p&#x2F;f9e53442c85d</a>).<p>I’d love to hear your thoughts — especially where you think this model could shine, any production concerns, similar patterns or tools you’ve seen in practice.<p>Feel free to reach me as <i>ymz-ncnk</i> on the Gophers Slack or follow <a href="https:&#x2F;&#x2F;x.com&#x2F;cmdstream_lib" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;cmdstream_lib</a> for project updates.

[IDE/Editor] Show HN: Lotas – Cursor for RStudio Hey HN! We’re Jorge and Will from Lotas (<a href="https:&#x2F;&#x2F;www.lotas.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.lotas.ai&#x2F;</a>), and we’ve built an AI coding assistant into RStudio (think Cursor for RStudio).<p>RStudio is used by about 2 million data scientists and academics, but they currently lack a coding assistant within their IDE. Developers in other environments benefit from tools like Cursor and Windsurf, but R users don’t have any equivalent tools to speed up their workflow. Since ~80% of R programmers prefer to use RStudio over other IDEs like VSCode to write R code, we figured a tool like this one could be quite useful.<p>Both of us were PhD students at Harvard. Jorge was in the biophysics program and Will was in the biostatistics program where most people used RStudio every day. We saw how integrated code assistants were taking off in other IDEs, but we noticed that the RStudio integrations were still lagging far behind. Many R users were copying and pasting code from ChatGPT to build their workflows, and this was clearly slow and fragile.<p>To bring the Cursor-like experience to RStudio users, we built Rao (<a href="https:&#x2F;&#x2F;www.lotas.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.lotas.ai&#x2F;</a>): a fork of RStudio with an embedded AI assistant that is aware of the user’s local context (both files and variable environment), can read and write files, can run code or commands, and can interpret textual or visual output. It works with any of the file formats already in RStudio (R, notebooks including RMDs and QMDs, Python, Stan, etc.), allowing R programmers to iteratively perform entire data analyses inside their preferred IDE.<p>Other AI data science tools are either (1) built on the web or in environments people don’t already use, (2) are completely focused on python notebooks, or (3) are weak package-based assistants with limited functionality. Rao is exactly like the RStudio IDE that millions of data scientists already use, but it incorporates a powerful AI assistant and works with all the standard file types.<p>You can download Rao at <a href="https:&#x2F;&#x2F;www.lotas.ai&#x2F;download" rel="nofollow">https:&#x2F;&#x2F;www.lotas.ai&#x2F;download</a>, watch our demo on the homepage (<a href="https:&#x2F;&#x2F;www.lotas.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.lotas.ai&#x2F;</a>), and work through some example use cases on our GitHub (<a href="https:&#x2F;&#x2F;github.com&#x2F;lotas-ai&#x2F;rao&#x2F;tree&#x2F;main&#x2F;demos">https:&#x2F;&#x2F;github.com&#x2F;lotas-ai&#x2F;rao&#x2F;tree&#x2F;main&#x2F;demos</a>). We have a one-week free trial (no card required) and provide 500 queries&#x2F;month for $20&#x2F;month after that. We’d love to hear feedback from the HN community to make Rao as useful as possible! You can reach us at founders@lotas.ai.<p>P.S. We have zero data retention (ZDR) agreements with OpenAI and Anthropic, but we currently recommend users do not input sensitive or regulated data like PHI into Rao until we sign BAAs with both model providers.

[Other] Show HN: MCP Jetpack – The easiest way to get started with MCP in Cursor My friends and I built MCP Jetpack which makes it really easy to start using MCP. It’s an MCP server that automatically finds and executes the right tools needed to accomplish your task without having to manage MCP servers for each service (GitHub, Linear, Atlassian, Notion etc.). Once you add it to Cursor (or any other AI app with MCP support), Cursor instantly gets access to a growing library of remote MCP servers without any extra setup. For services that require authentication, you will be asked to login the first time you ask your AI to interact with that service.<p>Two problems we are trying to solve:<p>Friction - Normally if you want to give Cursor access to GitHub, you have to install the right MCP server and login before you can use GitHub with Cursor’s chat. With MCP Jetpack, you can ask Cursor to list your GitHub issues, and it will automatically execute the right tool behind the scenes to accomplish your task. For services that require authentication, you will be asked to login the first time you interact with the service. However, it all happens within the Cursor chat so you never have to context switch and fiddle with Cursor’s settings.<p>Tool Limits - Cursor warns you if you have more than 50 MCP tools installed as it says having more will degrade performance. However, just installing the GitHub MCP server itself adds 74 MCP tools. With MCP Jetpack, you get access to GitHub, Atlassian and 15 other services with just two tools: “FindTool” and “ExecTool”.<p>Here are the 17 services we support today: GitHub, Atlassian, Canva, Linear, Notion, Intercom, Monday.com, Neon, PayPal, Hugging Face, Sentry, Square, Webflow, Wix, Cloudflare Docs, Cloudflare AI Gateway, Cloudflare Workers Bindings.<p>We’ll continue to add more services as companies launch remote MCP servers.

Years ago, to manage this work securely and get a clear audit trail, we built an internal platform we call &quot;Hub.&quot; It&#x27;s essentially a locked-down environment where our team works that records their sessions, tracks every interaction, and prevents data from being copied or shared. It&#x27;s been our internal source of truth for years.<p>More recently, like many companies, we&#x27;ve been building more automation. And like everyone else, we&#x27;ve seen our automations fail on edge cases—a weirdly formatted invoice our parser can&#x27;t read, a website layout change that breaks a scraper, etc. Our team would have to manually step in to fix these.<p>We realized other developers must have this exact same problem, but without a 250-person team on standby. So we connected our old, battle-tested Hub to a new, modern front door: a Human-in-the-Loop (HITL) API. We&#x27;re calling it browser-work.com.<p>The idea is simple: when you hit a task that needs a human, you can send it to our team through the API.<p>Here&#x27;s how it works:<p><pre><code> - You POST a request to our endpoint. The payload contains the context for the task (like a URL) and a set of instructions for the human on what to do. - The task appears in the Hub, where one of our trained operators can claim it. - They perform the task exactly as instructed, all within the secure Hub environment. - When they&#x27;re done, we send a webhook to your system. The return payload includes the task&#x27;s output, any notes left by the human, and a detailed log of their actions (e.g., DOM elements they interacted with). </code></pre> For example, if your automation for paying a utility bill fails, you can pass the task to us. A person will log in, navigate the portal, make the payment, and return a confirmation number.<p>The product is live and we&#x27;re looking for people with interesting use cases.<p>I&#x27;m Robert, the CIO. If this sounds useful to you, send me a brief email about your use case at robert@apmhelp.com and we can get you started right away.<p>Happy to answer any questions here.

[Other] Show HN: Context42 – capture your coding style from across your projects Show HN: Context42 - AI-powered style guide generator for your codebase<p>Hey HN,<p>I&#x27;ve been building Context42 to solve a problem that&#x27;s been bugging me: getting AI to write code like me, and helping disseminate coding best practices.<p>The core insight is simple - your existing code is already your best style guide. Instead of debating tabs vs spaces or where to put your curly braces, Context42 analyzes your actual codebase and generates comprehensive style documentation using Google&#x27;s Gemini AI.<p>Here&#x27;s what makes it special:<p>1. *Language-aware analysis* - It groups files by language and generates specific style guides for each. Your TypeScript patterns won&#x27;t bleed into your Python conventions.<p>2. *Dependency-smart processing* - It analyzes child directories before parents, building up context as it goes. This means it understands your module structure and can identify patterns that emerge across your architecture.<p>3. *Built for real codebases* - With configurable concurrency, resume capability, and automatic cleanup, it&#x27;s designed to handle everything from small projects to massive monorepos. The terminal UI (built with Ink&#x2F;React) gives you real-time progress on what&#x27;s happening.<p>4. *Pragmatic over prescriptive* - Instead of enforcing arbitrary rules, it documents what you&#x27;re already doing. This makes it easier to onboard new developers and maintain consistency without religious debates.<p>The technical approach is interesting too - it uses a worker pool pattern with abort controllers for graceful shutdown, SQLite for persistence (so you can resume failed runs), and a file registry system that guarantees cleanup even on crashes.<p>I built this because I believe the best documentation is the kind that reflects reality, not aspirations. Your code style isn&#x27;t what you think it should be - it&#x27;s what it actually is. And that&#x27;s worth documenting.<p>You can check it out at: <a href="https:&#x2F;&#x2F;github.com&#x2F;zenbase-ai&#x2F;context42">https:&#x2F;&#x2F;github.com&#x2F;zenbase-ai&#x2F;context42</a><p>Would love to hear your thoughts, especially if you&#x27;ve tackled similar problems in your teams.

[Other] Show HN: Compass CNC – Open-source handheld CNC router Hey HN,<p>I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process.<p>The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts.<p>What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for &lt;$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope.<p>We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;camchaney&#x2F;handheld-cnc">https:&#x2F;&#x2F;github.com&#x2F;camchaney&#x2F;handheld-cnc</a>

[Other] Show HN: Object database for LLMs that persists across chats (MCP server) I’d like to use LLMs for remembering all kinds of things: fitness, to-do lists, contacts, bug reports, research links, whatever. But there is no way to do that now.<p>For example, if I find a great coding tutorial in chat, or tell it how much I ran yesterday, it forgets that when I close the chat. Even if I keep the chat history, I still need to scour through lots of messages to find the data I want. Ideally, Claude would remember all this, and I’d be able to find it later with ease. This is what my team built.<p>It is a collaborative database you add to any LLM that supports MCP. (Claude Code, Desktop, and Pro for now; ChatGPT will soon). You can add, update, and search for items in the database inside chat. You can easily create your own object schemas. There is an automatically generated web UI for using the database. It generates maps, charts, calendars, tables, lists, and other UI elements. You can share or publish the database as well.<p>Over time, we want to make this database powerful enough to make our lives much simpler by letting LLMs replace a bunch of the apps and software services we use daily.

[Other] Show HN: kiln – Git-native, decentralized secret management using age Hi HN, I&#x27;ve been building this tool for the past couple of weeks to solve a problem that seems universal across development teams: sharing environment variables securely.<p>You know the drill - someone needs the staging database URL, so it gets shared over chat. Production API keys end up in plaintext files. Or you set up some complex secret management system that becomes a single point of failure during critical deployments.<p>At Zerodha, we&#x27;re a stock broker with strict regulatory requirements. Our infrastructure needs to be auditable, and our data must stay with us for instant recovery. But the deeper issue was that every solution we tried made deployments dependent on external services.<p>We tried GitLab CI&#x27;s built-in secrets, but they&#x27;re stored unencrypted and only repository maintainers can access them. HashiCorp Vault was too complex to manage with painful ACL setup, plus it&#x27;s now crippled by their BSL license change. AWS Secrets Manager would create the vendor lock-in we wanted to avoid.<p>The breaking point came when we wanted to manage secrets through Terraform for idempotency and better infrastructure-as-code practices. But Terraform has no built-in way to encrypt secrets without relying on external providers. We could either store secrets in plaintext in our Terraform configs or add yet another external dependency to our deployment pipeline.<p>That&#x27;s when I had the idea: what if we could inject encrypted environment variables directly into Terraform, so anyone with the right key could deploy without hunting down secrets from different systems? As I iterated through this idea, I realized the same pattern would work for any application - from personal projects to team deployments.<p>So I built kiln. It encrypts environment variables using age encryption into files that live alongside your code. No servers, no network calls, no external dependencies. Each team member gets their own key, and you control access per environment.<p>Here&#x27;s how it works:<p><pre><code> # Generate a new age key, or use your existing SSH keys kiln init key # Initialize with your team&#x27;s public keys kiln init config --recipients &quot;alice=$(curl https:&#x2F;&#x2F;gitlab.company&#x2F;alice.keys)&quot; --recipients &quot;me=$(cat ~&#x2F;.ssh&#x2F;id_ed25519.pub)&quot; # Set secrets (prompts securely, never shows in terminal) kiln set DATABASE_URL kiln set API_KEY # Run your app with decrypted environment kiln run npm start # These encrypted files are safe to commit git add .kiln.env kiln.toml </code></pre> Why not SOPS? SOPS is great for general file encryption, but kiln is built specifically for the environment variable workflow. It has commands like &quot;run&quot;, &quot;export&quot;, and built-in team management. Think &quot;SOPS for .env files&quot; with a focus on developer UX.<p>Why not raw age encryption? Age is perfect for the crypto layer, but terrible for day-to-day team workflows. Try managing 20 team members across 5 environments with raw age commands - you&#x27;ll go insane. kiln handles the orchestration.<p>As for technical details, kiln:<p>- Uses age encryption (modern, audited, simple)<p>- Works with existing SSH keys or generates new age keys<p>- Role-based access via TOML configuration<p>- Single, cross-platform Go binary<p>- Zero network dependencies - everything works offline<p>- MIT licensed<p>The game-changer: secrets travel with code. No more &quot;can someone send me the staging secrets?&quot; in chat. No more broken deploys because the secret service is down. No more hoping your vendor doesn&#x27;t change their pricing or licensing.<p>Try it out - I&#x27;m confident it&#x27;ll help improve your team&#x27;s deployment workflows.

[Other] Show HN: A 'Choose Your Own Adventure' written in Emacs Org Mode I authored and developed an interactive children&#x27;s book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story.<p>Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story.<p>The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend.<p>Ten Dollar Adventure: <a href="https:&#x2F;&#x2F;tendollaradventure.com" rel="nofollow">https:&#x2F;&#x2F;tendollaradventure.com</a><p>Sample the Web Book (one complete storyline&#x2F;adventure): <a href="https:&#x2F;&#x2F;tendollaradventure.com&#x2F;sample&#x2F;" rel="nofollow">https:&#x2F;&#x2F;tendollaradventure.com&#x2F;sample&#x2F;</a><p>I couldn&#x27;t muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.<p>Twiorg: <a href="https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;twiorg">https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;twiorg</a><p>ox-twee: <a href="https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;ox-twee">https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;ox-twee</a><p>Previous HN post on writing the transaction logic using an LLM in Emacs: <a href="https:&#x2F;&#x2F;blog.tendollaradventure.com&#x2F;automating-story-logic-with-llms&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.tendollaradventure.com&#x2F;automating-story-logic-w...</a><p>Twinery 2: &lt;<a href="https:&#x2F;&#x2F;twinery.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;twinery.org&#x2F;</a>&gt; and discussion on HN: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32788965">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32788965</a>

[DevOps] Show HN: GitGuard - Painless GitHub PR Automations Hey HN,<p>Every team I&#x27;ve been on has cobbled together some sort of combination of GitHub branch protections and custom scripts to make sure that PRs conform to organization policies and best practices.<p>Things like:<p>- When {X} file is changed, require review from team {Y}<p>- When a new db migration is added, ensure that a special set of tests pass<p>- Require multiple approvals when the PR is very large<p>- Add a special label to PRs that include breaking changes<p>- Allow emergencies &#x2F; hotfixes to break glass and bypass all of the above<p>Most teams tend to start out with a little script running in GitHub actions to enforce all of these policies but it tends to get out of hand and become hard to maintain. PRs that should require scrutiny slip through the cracks, and others that should be allowed through are unnecessarily blocked.<p>That&#x27;s why I made GitGuard (<a href="https:&#x2F;&#x2F;gitguard.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;gitguard.dev&#x2F;</a>)<p>GitGuard lets you write and maintain these policies in a custom DSL so simple it looks like pseudocode. The policies are checked on every single PR nearly instantly (no need to wait for a GitHub actions runner) and the results are reported in plain english.<p>Right now policies can make simple assertions about PR metadata and take some stateful actions (adding labels, requesting review) but I&#x27;d love to hear more from HN about how GitGuard could be even more useful.

[Other] Show HN: Improving RAG with chess Elo scores Hello HN,<p>I&#x27;m Ghita, co-founder of ZeroEntropy (YC W25). We build high accuracy search infrastructure for RAG and AI Agents.<p>We just released two new state-of-the-art rerankers zerank-1, and zerank-1-small. One of them is fully open-source under Apache 2.0.<p>We trained those models using a novel Elo score inspired pipeline which we describe in detail in the blog attached. In a nutshell, here is an outline of the training steps: * Collect soft preferences between pairs of documents using an ensemble of LLMs. * Fit an ELO-style rating system (Bradley-Terry) to turn pairwise comparisons into absolute per-document scores. * Normalize relevance scores across queries using a bias correction step, modeled using cross-query comparisons and solved with MLE.<p>You can try the models either through our API (<a href="https:&#x2F;&#x2F;docs.zeroentropy.dev&#x2F;models">https:&#x2F;&#x2F;docs.zeroentropy.dev&#x2F;models</a>), or via HuggingFace (<a href="https:&#x2F;&#x2F;huggingface.co&#x2F;zeroentropy&#x2F;zerank-1-small" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;zeroentropy&#x2F;zerank-1-small</a>).<p>We would love this community&#x27;s feedback on the models, and the training approach. A full technical report is also going to be released soon.<p>Thank you!

[CLI Tool] Show HN: DataRamen, a Fast SQL Explorer with Automatic Joins and Data Navigation I built DataRamen, a local-first SQL explorer that helps you get the data you need fast, without writing repetitive queries every time.<p>You run it locally from the CLI (no cloud version yet), connect your databases, and you&#x27;re ready to go. The goal is to let you explore and query data like you would in a spreadsheet: intuitive, fast, and without friction.<p>Key features:<p>- Automatic joins &amp; related data navigation: Right-click any row to instantly see related records in other tables (based on foreign keys or references).<p>- Keyboard-driven UI: Hit N to jump to a table, F to filter, and so on, it’s optimized for speed so you can go from question to insight in seconds (this point is still in progress, I find it confortable, but the goal is to make it even better).<p>- Named tabs with saved queries: Keep multiple tabs open with different queries, useful for comparing or cross-checking data. Tabs are saved, so you can get back to your queries at any time.<p>- Instant edit &amp; insert: One click to edit or add rows, no need to write full queries.<p>- Multi-DB support: Connect several databases and search across all of them.<p>- Search across all columns: Find what you need even if you don&#x27;t know the exact column.<p>If you&#x27;ve ever felt slowed down by writing the same SQL over and over just to explore your data, this might save you a ton of time.

[Other] Show HN: I built a dream interpreter in JavaScript, no AI, no server, just logic I built a browser-only dream interpreter that maps symbols to meaning using a custom keyword engine. No AI, no tracking, no backend it’s all deterministic logic, built with vanilla JavaScript. The idea was to see if emotional and symbolic interpretations could still feel personal without using machine learning. Dreams are parsed against a map of 300+ symbolic meanings. Everything runs locally in your browser and saves via localStorage. You can revisit old dreams, reflect on interpretations, or just explore what the system sees in your subconscious. Happy to answer questions, would love feedback!

[Other] Show HN: I built a tool to sync localStorage between devices At my day job, we have a daily async stand-up. We have to message a slack bot how many hours we have worked on a given task that day and overall.<p>The format is:<p>&gt; Task: &quot;Task Name&quot; | Worked: 5h Total: 16h &gt; Description: Finished implementation of feature.<p>I don&#x27;t complain. Most fully remote jobs come with a version of this, but doing it manually got tedious. So, I needed a simple app that would track this.<p>I am not usually a fan of &quot;vibe coded&quot; apps, but this was an ideal candidate for it, since it&#x27;s not production code. Most LLMs solve the problem by creating a single HTML file with forms that save data to localStorage. This was perfect for me - no hosting, no DB, no backend. Just 15 mins of prompting.<p>One day I was outside, just with my phone, and of course I couldn&#x27;t use the app. I thought &quot;how hard can it be to synchronize localStorage data across devices?&quot;. Turns out, it&#x27;s not that hard, if you are ready to build a whole platform around it.<p><a href="https:&#x2F;&#x2F;htmlsync.io" rel="nofollow">https:&#x2F;&#x2F;htmlsync.io</a> does just that. You upload your HTML app that works with localStorage and get a subdomain for it. The tool automatically synchronizes your changes across devices. You can create private and public apps, can decide which keys to synchronize by using the &quot;no_sync_&quot; prefix. The &quot;public-hidden&quot; CSS class can be used to hide UI elements in public view. You also get a subdomain for your profile where all your apps are listed for easy access.<p>I hope you find this as useful as I did.<p>I&#x27;d also appreciate your feedback if you end up using it.

[Database] Show HN: OrioleDB Beta12 Features and Benchmarks Hey HN, I&#x27;m the creator of OrioleDB, an extension for PostgreSQL that serves as a drop-in replacement for the default Heap storage engine. It is designed to address scalability bottlenecks in PostgreSQL&#x27;s buffer manager and reduce the WAL, enabling better utilization of modern multi-core CPUs and high‑performance storage systems.<p>We are getting closer to GA. This release includes:<p>- An index bridge to support all indexes that Heap supports<p>- Support for rewinding recent changes in the database.<p>- Tablespaces support<p>- Fillfactor support<p>- An orioledb_tree_stat() function for space utilization statistics<p>- Support for tables with more than 32 columns.<p>We also show several performance improvements using the TPC-C benchmarks. Overall, OrioleDB is much faster than Heap, also outperforming other Postgres providers.<p>We would love more people testing OrioleDB.

[Other] Show HN: Timep – a next-gen profiler and flamegraph-generator for bash code timep is a TIME Profiler for bash code that will give you an accurate per-command execution time breakdown of any bash script or function.<p>Unlike other profilers, timep also recovers and hierarchally records metadata on subshell and function nesting, allowing it to recreate the full call-stack tree for the bash code being profiled. If you call timep with the `--flame` flag, it will automatically generate a flamegraph .svg image where each block represents the wall-clock time spent on a particular command (top level) or its parent subshells&#x2F;functions (all the other levels).<p>Using timep is simple - just source the timep.bash file then add timep before whatever you want to profile. You do not need to change in the code being profiled - timep handles everything for you. Example usage:<p><pre><code> . .&#x2F;timep.bash timep someFunc timep -flame someScript &lt;inputFile </code></pre> timep will generate 2 profiles for you: one showing each individual command (with full subshell&#x2F;function nesting chains), and one that combines repeated loops commands into a count + total runtime line with minimal &quot;extra&quot; metadata.<p>See the github README for more info on the available flags and output profile specifics.<p>timep works by cramming all the timing instrumentation logic into a DEBUG trap that roughly does the following:<p>1. record end timestamp for previous command 2. compare current state to state saved in variables last DEBUG trap to determine what sort of command is happening. e.g., if BASH_SUBSHELL increased then we know we just entered a subshell or background fork. 3. once we know what type of command is happening, generate a log line for the previous command (now that we have its end time 4. save current state in various variables (for use next debug trap) 5. record start time for the next command<p>then after the profiled code is done running, timep post-processes the logs to produce the final profile

[Other] Show HN: CallFS – S3-style object store in one Go binary (MIT) We started CallFS after yet another late-night “why did the uploads vanish?” incident. Our small team had stitched together rsync, a fragile NFS mount, and an S3 bucket—none of it observable, all of it waiting to bite us.<p>So we wrote a single-process file service in Go that: • Speaks the S3 API (so existing tooling works). • Stores hot data on local disks for speed; cold data can sit in any S3-compatible bucket. • Exposes Prometheus metrics and JSON logs by default, because “what happened?” shouldn’t be guesswork. • Ships as a ~25 MB static binary—no external deps, MIT license.<p>Today it’s stable for single-node or side-by-side deployments. Clustering is on the roadmap, replication will follow, but we wanted to share the code early and hear real-world pain points. If storage glue code ever ruined your weekend, we’d love feedback and PRs.

I&#x27;ve used them in the past, but they&#x27;ve never been center-stage in my projects.<p>I wanted high cardinality keyword search for ANOTHER project... and, well, down the yak-shaving rabbit hole we go!<p>BloomSearch brings this into an extensible Go package:<p>- Very memory efficient via bloom filters and streaming row scans<p>- DataStore and MetaStore interfaces for any backend (can be same or separate)<p>- Hierarchical pruning via partitions, minmax indexes, and of course bloom filters<p>- Search by field, token, or field:token with complex combinators<p>- Disaggregated storage and compute for unbound ingest and query throughput<p>And of course, you know I had to make a custom file format ^-^ (FILE_FORMAT.MD)<p>BloomSearch is optimized for massive concurrency, arbitrary cardinality and dataset size, and super low memory usage. There&#x27;s still a lot on the table too in terms of size and performance optimizations, but I&#x27;m already super pleased with it. With distributed query processing I&#x27;m targeting &gt;100B rows&#x2F;s over large datasets.<p>I&#x27;m also excited to replace our big logging bill ~$0.003&#x2F;GB for log storage with infinite retention and guilt-free querying :P

You get a web push browser notification when it&#x27;s time, and clicking it takes you back to the post.

Wanted to revisit, but didn&#x27;t want to create even more bookmarks&#x2F;etc I&#x27;ll just forget about. So I created a &#x27;remind me later&#x27; tool (like the reddit bot) to fix this for myself.<p>To use it: go to hnping.com, enable notifications, and drag the bookmarklet to your bookmarks bar. Then click it on any HN post to set a reminder (5 minutes to 1 week). No personal info needed - you just get a UUID that serves as your account.<p>I tried to make it as simple as possible.<p>It&#x27;s built on a Cloudflare Worker with D1 for data storage and uses Firebase Cloud Messaging for push notifications.

[Other] Show HN: FluidAudio – Swift Speaker Diarization on CoreML We needed a speaker diarization solution that could run every few seconds alongside transcription on iOS and macOS. But native Swift support was either limited or locked behind paid licenses. Since diarization is a common need in speech-to-text workflows, we decided to open source our work and give back to the community.<p>We initially tried sherpa-onnx, which works, but running both diarization and transcription models slowed down older devices. CPU-only inference just isn’t ideal for near real-time workloads, so we wanted the option to offload segmentation and speaker embedding to the GPU or ANE. Supporting M1 Macs in particular meant pushing more of the workload to the ANE.<p>Instead of shoehorning the ONNX model into CoreML with C++, we converted the original PyTorch models directly to CoreML. This approach required some monkey-patching in the PyTorch and pyannote code, but the initial benchmarks look promising.<p>We’d love feedback! We&#x27;re currently working on adding VAD and integrating Parakeet for transcription, but still wrestling with CoreML model conversion.

[Other] Show HN: ArchGW – An intelligent edge and service proxy for agents Hey HN!<p>This is Adil, Salman and Jose and and we’re behind archgw [1]. An intelligent proxy server designed as an edge and AI gateway for agents - one that natively know how to handle prompts, not just network traffic. We’ve made several sweeping changes so sharing the project again.<p>A bit of background on why we’ve built this project. Building AI agent demos is easy, but to create something production-ready there is a lot of repeat low-level plumbing work that everyone is doing. You’re applying guardrails to make sure unsafe or off-topic requests don’t get through. You’re clarifying vague input so agents don’t make mistakes. You’re routing prompts to the right expert agent based on context or task type. You’re writing integration code to quickly and safely add support for new LLMs. And every time a new framework hits the market or is updated, you’re validating or re-implementing that same logic—again and again.<p>Putting all the low-level plumbing code in a framework gets messy to manage, harder to update and scale. Low-level work isn&#x27;t business logic. That’s why we built archgw - an intelligent proxy server that handles prompts during ingress and egress and offers several related capabilities from a single software service. It lives outside your app runtime, so you can keep your business logic clean and focus on what matters. Think of it like a service mesh, but for AI agents.<p>Prior to building archgw, the team spent time building Envoy [2] at Lyft, API Gateway at AWS, specialized NLP models at Microsoft Research and worked on safety at Meta. archgw was born out of the belief that rule-based, single-purpose tools that handle the work around resiliency, processing and routing prompts should move into a dedicated infrastructure layer for agents, but built on the battle-tested foundational of Envoy Proxy.<p>The intelligence in archgw comes from our fast Task-specific LLMs [3] that can handle things like agent routing and hand off, guardrails and preference-based intelligent LLM calling. Here are some additional details about the open source project. archgw is written in rust, and the request path has three main parts:<p>* Listener subsystem which handles downstream (ingress) and upstream (egress) request processing. * Prompt handler subsystem. This is where archgw makes decisions on the safety of the incoming request via its prompt_guard hooks and identifies where to forward the conversation to via its prompt_target primitive. * Model serving subsystem is the interface that hosts all the lightweight LLMs engineered in archgw and offers a framework for things like hallucination detection of our these models<p>We loved building this open source project, and our belief is that this infra primitive would help developers build faster, safer and more personalized agents without all the manual prompt engineering and systems integration work needed to get there. We hope to invite other developers to use and improve Arch. Please give it a shot and leave feedback here, or at our discord channel [4] Also here is a quick demo of the project in action [5]. You can check out our public docs here at [6]. Our models are also available here [7].<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;katanemo&#x2F;archgw">https:&#x2F;&#x2F;github.com&#x2F;katanemo&#x2F;archgw</a> [2] <a href="https:&#x2F;&#x2F;www.envoyproxy.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.envoyproxy.io&#x2F;</a> [3] <a href="https:&#x2F;&#x2F;huggingface.co&#x2F;collections&#x2F;katanemo&#x2F;arch-function-66" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;collections&#x2F;katanemo&#x2F;arch-function-66</a>...

[Other] Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com.<p>Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process.<p>And that&#x27;s not all.<p>Then came the pricing. The last quote I got for one of the tools on the market was $6,000&#x2F;year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous!<p>IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let&#x27;s experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I&#x27;m or my team is not using it.<p>Eventually I gave up looking for solution and decided to build it by myself.<p>Here it is: <a href="https:&#x2F;&#x2F;langfa.st" rel="nofollow">https:&#x2F;&#x2F;langfa.st</a><p>Help me find what&#x27;s wrong or missing or does not work from you perspctive.<p>P.S.

[Other] Show HN: RULER – Easily apply RL to any agent Hey HN, Kyle here, one of the co-founders of OpenPipe.<p>Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it&#x27;s so hard to implement.<p>One of the biggest challenges when adapting RL to a new task is the need for a task-specific &quot;reward function&quot; (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and&#x2F;or significant domain expertise to generate.<p>RULER is a drop-in reward function that works across different tasks without any of that complexity.<p>It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores within groups), it just works (surprisingly well!).<p>We have a full writeup on the blog, including results on 4 production tasks. On all 4 tasks, small Qwen 2.5 models trained with RULER+GRPO beat the best prompted frontier model, despite being significantly smaller and cheaper to run. Surprisingly, they even beat models trained with hand-crafted reward functions on 3&#x2F;4 tasks! <a href="https:&#x2F;&#x2F;openpipe.ai&#x2F;blog&#x2F;ruler">https:&#x2F;&#x2F;openpipe.ai&#x2F;blog&#x2F;ruler</a><p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;OpenPipe&#x2F;ART">https:&#x2F;&#x2F;github.com&#x2F;OpenPipe&#x2F;ART</a>

We also support BYOK (bring your own keys), so no $200&#x2F;month plans.<p>Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool!

Claude code works surprisingly well too.<p>Building the binary takes ~3 hours on our M4 Max MacBook.<p>--- Next? We&#x27;re just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!).

For sure its not for ms‑cycle loops, or uptime critical production stuff, but in applications with relaxed timing it allows for fast iteration on the setup - making prototyping a pleasure. Its easy to use, has no dependencies beside Python, its fully type annotated and MIT licensed. Internal it uses ModBus&#x2F;TCP for hardware communication, the implementation is exposed, so it co-serves as ModBus&#x2F;TCP client library.<p>I&#x27;d love to hear your use cases, feature ideas and PLC toolchain stories ;)<p>Docs: <a href="https:&#x2F;&#x2F;nonannet.github.io&#x2F;pyhoff" rel="nofollow">https:&#x2F;&#x2F;nonannet.github.io&#x2F;pyhoff</a>

[Code Quality] Show HN: I rewrote an outdated React Native map clustering library Hey Hacker News,<p>I&#x27;m a long-time lurker and wanted to share a project I just finished building.<p>Like many React Native developers, I needed to add marker clustering to a map in my app. The most popular library for this, react-native-maps-clustering, was fantastic in its day but has become outdated and no longer works with modern versions of Expo, React Native, and their dependencies.<p>After hitting a wall of compatibility issues, I decided to take on the challenge of rewriting it from the ground up, focusing on a modern toolchain and a better developer experience.<p>The journey was a lot more challenging than I anticipated. It turned into a deep dive into solving dependency hell with different versions of @types&#x2F;react, wrestling with build tool configurations for pnpm, bob, and ESLint, and ensuring everything was strictly typed with TypeScript. It felt like a classic case of yak shaving, but I was determined to create a solution that &quot;just works&quot; for developers today.<p>The result is RN Super Cluster, a performant, fully-typed, and easy-to-use clustering library for react-native-maps.<p>What it does: It provides a &lt;ClusteredMapView &#x2F;&gt; component that you can use as a drop-in replacement for the standard &lt;MapView &#x2F;&gt;. Any &lt;Marker &#x2F;&gt; components you place inside will be automatically clustered.<p>Key Features:<p><pre><code> Modern &amp; Maintained: Built with a modern toolchain and designed to be actively maintained. Fully-Typed: Written entirely in TypeScript to prevent common errors and improve autocompletion. High-Performance: Uses supercluster under the hood for extremely fast geospatial clustering. Spiderfier: At the maximum zoom level, overlapping markers automatically &quot;spiderfy&quot; (spread out on a spiral) so they can be individually tapped. Customizable: You can provide your own custom components for rendering clusters, and callbacks for handling press events. </code></pre> This was a passion project born out of necessity, and I hope it can save other React Native developers the headaches I went through.<p>I would love to get your feedback, and contributions are more than welcome!<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;suwi-lanji&#x2F;rn-maps-clustering">https:&#x2F;&#x2F;github.com&#x2F;suwi-lanji&#x2F;rn-maps-clustering</a> NPM: <a href="https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;rn-maps-clustering" rel="nofollow">https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;rn-maps-clustering</a><p>Thanks for checking it out!

[Other] Show HN: Dashboard tracking all GitHub PRs and analyzing Code Agent activity Hi HN,<p>We are researchers from ETH Zurich interested in the real-world adoption and impact of Code Agents.<p>To measure this, we built a dashboard, scraping all public PRs on GitHub, analyzing which are created by different code agents (Codex, Jules, Copilot, Devin, etc.), and measuring their merge rates, sliced by various repository and PR characteristics.<p><a href="https:&#x2F;&#x2F;insights.logicstar.ai" rel="nofollow">https:&#x2F;&#x2F;insights.logicstar.ai</a><p>Since mid-May, we&#x27;ve analyzed over 10 million PRs and already found some interesting trends:<p>Usage is high, but shallow. Agents submit ~7% of all PRs overall, but only ~1–2% on popular repos. Most activity is in low-star or experimental projects.<p>Merge rates vary drastically. On low-traffic repos, some agents get 90%+ of their PRs merged. On popular projects, that can drop to &lt;25%.<p>Pre-review helps. Agents that require human-in-the-loop review (e.g., Jules, Codex) have 30–50% higher merge rates than Copilot-style fire-and-forget PRs.<p>Bias toward new code. Agent PRs mostly add code. Refactorings and deletions are rare.<p>If you have ideas for what other characteristics we should look at let us know or play with the code yourself

[Other] Show HN: Smart Switcher - data driven tool to improve the window switching Hello, my name is Andrew. I&#x27;m an indie developer and I&#x27;m excited to release Smart Switcher for Windows 10&#x2F;11. I&#x27;m looking for feedback on the overall project and the application itself.<p>I built this because I couldn&#x27;t find a window switching&#x2F;management solution that worked for me. I tried all kinds of different solutions, virtual desktop extensions, obscure GUI window managers, you name it. Overtime I realized I wanted something that prioritizes one window at a time, is keyboard driven with has minimal if no GUI elements. I figured this part out, but knew something was missing. I had my eureka moment when I realized I could combine my switching method with a prediction algorithm. This led to the creation of Smart Switcher.<p>Smart Switcher is a data driven window switcher aimed at improving the overall window switching experience. It logs data on your windows switching, then a prediction algorithm analyzes this data and uses it to predict which window you would want to switch to next. When you need to switch windows, you press the switch shortcut to switch to the next predicted window. If this isn&#x27;t the window you wanted, press the override shortcut to switch to the next most likely window. You can press the override shortcut as many times as needed until you arrive at your desired window.<p>It’s a paid app with a demo and trial version. There is a introductory discount and some additional discount tiers for early adopters.<p>Any feedback is appreciated! Thanks!

This time, I made something for a very specific use case: solving chess puzzles with no internet.<p>Why? Well, my Wi-Fi is terrible in the bathroom—and that&#x27;s where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess.<p>OffChess is an iPhone&#x2F;Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1&#x2F;2&#x2F;3&#x2F;4&#x2F;5, tactics like pins&#x2F;forks&#x2F;skewers, or openings like Sicilian&#x2F;French, etc). You gain or lose points based on how you perform, so there&#x27;s a light rating system to keep things engaging.<p>No accounts, no tracking, no monthly subscriptions, no internet required.

[DevOps] Show HN: GraphFlow – A lightweight Rust framework for multi-agent orchestration It all started with a conversation among friends about limitations in current multi-agent orchestration frameworks. We faced issues like limited control over agent memory and state, complicated persistence, scaling problems, and lack of type safety in Python-based tools. These challenges inspired us to try something different. The result was GraphFlow, a Rust-based lean framework for orchestrating multi-agent workflows that&#x27;s simple, scalable, and robust. Its key features include: Graph-based orchestration: Easily define workflows using nodes and edges. Lean Execution Engine: A minimal and efficient graph executor &#x2F; state machine implementation. Clear Memory Management: Direct and transparent handling of agent states. Simple DB Schema: Easy-to-understand schema for persistence and state tracking. High Performance: Native Rust performance with low overhead and easy scaling. Type Safety: Rust&#x27;s type system reduces runtime errors. GraphFlow is open-source ofc and aims to solve real-world problems we&#x27;ve experienced firsthand. We&#x27;d love your feedback!

[Other] Show HN: ParsePoint – AI OCR that pipes any invoice straight into Excel Hi HN,<p>I run a small ecommerce shop and, until recently, spent way too many evenings copy-pasting supplier invoices into Excel so my books stayed clean and my expense tracking was granular. It finally hit me that I’d rather invest that time in code than in Ctrl-C&#x2F;Ctrl-V, so I built ParsePoint.app.<p>Why I built it • Manual invoice entry was swallowing 4 hours every month. • Accounting software APIs felt heavyweight for my use-case; I really just wanted clean rows in a spreadsheet. • I love tinkering with AI models and needed an excuse to spin one up in production.<p>What it does 1. Upload a PDF (or forward an email). 2. ParsePoint’s AI OCR extracts line-items, amounts, tax, dates, etc. 3. Download a ready-to-pivot Excel&#x2F;CSV file or hit the API to drop the data wherever you like.<p>Under the hood • Frontend: React • API: .NET 8, PostgreSQL • AI layer: an open-source VLLM model fine-tuned for document layouts<p>Outcome so far • My own workload: from 4 hours&#x2F;month to less than 10 minutes. • Early beta testers (other solo-store owners) report similar time savings and fewer bookkeeping errors. • The pay-as-you-go credit system means no subscriptions or lock-ins—use it only when you need it.<p>I’d love feedback on the tech approach, pricing model, or anything that looks off. All comments welcome, and I’m here to answer every question.<p>Thanks for reading! Marcin – maker of ParsePoint.app

[Other] Show HN: Ncrypt – Query encrypted files privately with FHE Hey HN,<p>We&#x27;re building ncrypt, an open-source encrypted file manager that allows you to store, manage, and privately query your files using fully homomorphic encryption (FHE). This project originally started as a simple SFTP-like CLI for my personal S3 buckets which I used to send and retrieve encrypted files and have more granular control over key rotation.<p>As the number of files that I was storing grew, file discovery started to become a problem, and I found myself frequently having to download and decrypt files to inspect their contents. Rather than leaving them unencrypted in S3 and therefore easier to search, I started looking into the concept of searching over encrypted data using fully homomorphic encryption. This led me to Zama&#x27;s concrete-python library (<a href="https:&#x2F;&#x2F;github.com&#x2F;zama-ai&#x2F;concrete">https:&#x2F;&#x2F;github.com&#x2F;zama-ai&#x2F;concrete</a>), which provides a simple Python interface for performing FHE operations.<p>FHE is notoriously slow, so rather than trying to search over entire files I focused on a more tractable problem, indexing and searching over file metadata (summaries, keywords, embeddings, etc) which was small enough to make search practical. While still not fast compared to traditional file management tools, ncrypts search performance is decent if you keep directory sizes relatively small (under 25 files), and most of the heavy lifting happens during metadata extraction, not at search time.<p>The two types of encrypted queries we currently support are keyword search and cosine similarity search over vector embeddings, which are generated using user-specified huggingface models. Ncrypt currently supports metadata extraction for text, image, and audio files. Check out our code and give it a try at <a href="https:&#x2F;&#x2F;github.com&#x2F;ncryptai&#x2F;ncrypt">https:&#x2F;&#x2F;github.com&#x2F;ncryptai&#x2F;ncrypt</a>.<p>We love feedback!

[Other] Show HN: Mochia, a virtual pet browser game, built with Rust, SolidJS, Postgres Around three years ago, I was reminiscing about how much I loved playing Neopets as a kid. Meanwhile, I was also looking for a project to better learn Rust and SolidJS. So.. I figured making my own virtual pet browser game would be a fun way to practice! Since then, I’ve been working on it nearly every day, and.. it’s grown quite a bit! Here are some bulleted lists for your convenience:<p>Technical Details:<p><pre><code> * Backend monolithic Rust server runs on a single $5&#x2F;month VPS * Lean frontend with just 3 dependencies (SolidJS, Solid Router, and Mutative) * Around 130,000 combined lines of code (frontend + backend) * Rust server uses axum, sqlx, tokio, rand, strum, tungstenite (websockets) * No server crashes or data loss in 3 years (thank you Rust + Postgres!) * Almost all graphics (500+ assets) are SVGs for perfect detail at every zoom level * Fully mobile responsive and playable on all modern browsers and devices * Actor model for player actions enables trivial parallel, multi-core scaling * Single page application that preloads entire game world on initial page load * Instantaneous navigation between pages (no additional page fetches required) * Lightweight game engine for minigames, powered by custom WebGL shaders * Rust is the single source of truth for data structures shared between browser and server * Custom derive macros used to autogenerate TypeScript bindings and binary decoding functions * Binary WebSocket messages with custom protocol for client-server communication * O(1) selection for nested, weighted-random item reward pools * Minigames can be played without an account (but rewards can&#x27;t be saved) </code></pre> Features:<p><pre><code> * Completely free to play with no ads or tracking * Multiplayer browser-based virtual world with 80+ locations to explore * Dark mode toggle switch * Simple minigames that smoothly run at your display&#x27;s refresh rate * Public leaderboards that track the top scores in each minigame * Pet training system with turn-based card-based battle arena * Dynamic player economy with player-run shops * Player guilds that members can level up to unlock perks * Abandoned mines area created by maze generation algorithm * Create &#x2F; adopt pets, adorn them with hats, give them pets, change their color, etc. * 220 items to collect (food, toys, cosmetics, books, charms, tiny creatures, etc.) * In-game currency with banking, auctions, stock market, and jobs system * Villagers you can talk to, befriend, and complete quests and jobs for * Optional push notifications (like for when you win an auction) * 38 achievement avatars to unlock * Social features: befriend others, send gifts, and share your recent activity * NPC shops that restock over time (sometimes with very rare items!) * Luck system with ways to boost your luck for better rewards * Many puzzles that grant items or MP (currency) when solved * Fishing, gardening, caves, random events, fountains, galleries, etc. * Wheels to spin, treasure maps to complete, and secrets to explore! * Much, much more but I don&#x27;t want to spoil everything! </code></pre> Links:<p><pre><code> * Website URL: https:&#x2F;&#x2F;mochia.net * Community Discord: https:&#x2F;&#x2F;discord.gg&#x2F;ub6z8YH866 * Gameplay Video: https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=CC6beIxLq8Q * Screenshots Album: https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;FC9f9u3 </code></pre> I&#x27;d love to answer any questions, hear any thoughts, or read any sort of feedback or criticism!

[Other] Show HN: Recivo – Receive Emails Programmatically Hi HN, these last couple of weeks I&#x27;ve been building &#x27;Recivo&#x27;, a simple way to receive emails programmatically. There are plenty of API-based services that can be used to send emails, but receiving them is harder.<p>As a Recivo user, you create a new email address which will then immediately be available for receiving emails. A REST `&#x2F;inbox` endpoint is exposed for retrieving these emails, this includes all data you would expect: subject, content, sender, and most importantly: attachments. You can also get notified of newly received emails using webhooks.<p>The main use-cases I&#x27;m thinking of right now is triggering AI agents using email or a very simple document upload flow to any SaaS (just forward an email to the SaaS). This is actually where the inspiration for Recivo came from, I really enjoy the flow of getting an invoice in my mailbox and forwarding it to my accounting software and then seeing it appear in the app. The agentic use-case seems promising, especially for workflows that still require a human in the loop. Asynchronous communication with an AI agent feels natural to me.<p>When you visit the landing page you&#x27;re immediately given a randomly generated email address and a cURL command to try the API. Of course these demo addresses will expire, so you&#x27;ll have to log in to create a non-randomized and permanent address.<p>I&#x27;m wondering if you see any other use cases for a &quot;programmatic&quot; mailbox. Please let me know what you think!

[Other] Show HN: CSS generator for a high-def glass effect There are lots of glassmorphism generators out there, but I wanted to push the effect further! This project is the result of months of experimenting with CSS property layering and battling browser quirks.<p>Cross-browser compatibility is actually the reason I rely on ::before and ::after pseudo-elements to build up the effect. Move the color&#x2F;opacity to the main element, and you’ll get weird color bleed on the corners in Chrome. Move the texture, and it muddles the bevel’s specular highlight. Move the bevel, and it gets blurred out by the backdrop-filter. And so on!<p>Layers include: * Adjustable blur, brightness, and saturation (backdrop-filter) * Subtle translucent texture * Faux 3D bevel (using box-shadows, not an outline)<p>Glassmorphism is rather heavy on resources, so it’s best used as an accent and avoided on wide desktop elements. Should be compatible with recent versions of Chrome, Safari, and Firefox (desktop and mobile). If you spot bugs or rendering glitches, I’d love to know!<p>Side note: this is an early preview of a framework-agnostic glass SCSS&#x2F;component library I’m building.

[Other] Show HN: I built the tool I wished existed for moving Stripe between countries In late 2024, I had to set up a new Stripe account because I incorporated my company in a different country. Turns out it&#x27;s not as simple as just changing the country in a dropdown, you have to start from scratch.<p>I had hundreds of users and using Stripe&#x27;s dashboard to add all of the products, prices, coupons and subscriptions manually would take ages. I contacted a couple of services that help with this kind of migration, but their quotes were way over my budget. My next option was to use Stripe&#x27;s API, which is very powerful but also very complicated. I&#x27;m a designer who can code, but I didn&#x27;t feel confident doing it alone, so I asked a friend, an experienced developer, to help.<p>It proved to be quite challenging, with many details and caveats we had to learn as we went. What we thought would take a couple of days took us a week.<p>After this experience, we teamed up and built <a href="https:&#x2F;&#x2F;stripemove.com" rel="nofollow">https:&#x2F;&#x2F;stripemove.com</a>, a tool that guides you through this whole process, explaining and automating that hard week we went through. It handles the technical complexity while keeping your business running. Customers keep paying on your old account while everything transfers in parallel, then you flip the switch when ready.<p>It&#x27;s a very niche tool, built for founders who need to change their company location for personal or business reasons. For entrepreneurs buying companies established in other countries. For people in the same situation I was in a few months ago. Basically the tool I wished existed, and for a fair price. Designed to get you through this inconvenient process and back as soon as possible on growing your business.<p>Would love to hear from anyone who&#x27;s dealt with similar Stripe migrations. What was your biggest pain point?

It’s written in C++ 17 with thin Python bindings, keeps the exact same BPE vocab&#x2F;special-token rules, and focuses on raw speed.<p>I’m teaching myself LLM internals by re-implementing the stack from first principles. Profiling TikToken’s Python&#x2F;Rust implementation showed a lot of time was spent doing regex matching. Most of my perf gains come from a) using a faster jit-compiled regex engine; and b) simplifying the algorithm to forego regex matching special tokens at all.<p>Benchmarking code is included. Notable results show: - 4x faster code sample tokenization on a single thread. - 2-3x higher throughput when tested on a 1GB natural language text file.

Octelium, as described more in detail in the repo&#x27;s README, is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It can operate as a remote access&#x2F;corporate VPN (i.e. alternative to Twingate, Tailscale, OpenVPN Access Server, etc...), a ZTNA&#x2F;BeyondCorp platform (i.e. alterntive to Cloudflare Access, Teleport, Google BeyondCorp, etc...), and it can also operate as an API&#x2F;AI gateway, an infrastructure for MCP and A2A architectures and meshes, an ngrok alternative, a homelab infrastructure or even as a more advanced Kubernetes ingress. It&#x27;s basically designed to operate like a unified Kubernetes-like scalable architecture for zero trust secure&#x2F;remote access that&#x27;s suitable for different human-to-workload and workload-to-workload environments.

Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solution!<p>The code example is a bit verbose, so I encourage you to take a look at the repo&#x27;s README. I look forward to hearing your thoughts, or any usecases you may come up with!

[Testing] Show HN: Magnitude – Open-source AI browser automation framework Hey HN, Anders and Tom here. We had a post about our AI test automation framework 2 months ago that got a decent amount of traction (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43796003">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43796003</a>).<p>We got some great feedback from the community, with the most positive response being about our vision-first approach used in our browser agent. However, many wanted to use the underlying agent outside the testing domain. So today, we&#x27;re releasing our fully featured AI browser automation framework.<p>You can use it to automate tasks on the web, integrate between apps without APIs, extract data, test your web apps, or as a building block for your own browser agents.<p>Traditionally, browser automation could only be done via the DOM, even though that’s not how humans use browsers. Most browser agents are still stuck in this paradigm. With a vision-first approach, we avoid relying on flaky DOM navigation and perform better on complex interactions found in a broad variety of sites, for example:<p>- Drag and drop interactions<p>- Data visualizations, charts, and tables<p>- Legacy apps with nested iframes<p>- Canvas and webGL-heavy sites (like design tools or photo editing)<p>- Remote desktops streamed into the browser<p>To interact accurately with the browser, we use visually grounded models to execute precise actions based on pixel coordinates. The model used by Magnitude must be smart enough to plan out actions but also able to execute them. Not many models are both smart *and* visually grounded. We highly recommend Claude Sonnet 4 for the best performance, but if you prefer open source, we also support Qwen-2.5-VL 72B.<p>Most browser agents never make it to production. This is because of (1) the flaky DOM navigation mentioned above, but (2) the lack of control most browser agents offer. The dominant paradigm is you give the agent a high-level task + tools and hope for the best. This quickly falls apart for production automations that need to be reliable and specific. With Magnitude, you have fine-grained control over the agent with our `act()` and `extract()` syntax, and can mix it with your own code as needed. You also have full control of the prompts at both the action and agent level.<p>```ts<p>&#x2F;&#x2F; Magnitude can handle high-level tasks<p>await agent.act(&#x27;Create an issue&#x27;, {<p><pre><code> &#x2F;&#x2F; Optionally pass data that the agent will use where appropriate data: { title: &#x27;Use Magnitude&#x27;, description: &#x27;Run &quot;npx create-magnitude-app&quot; and follow the instructions&#x27;, }, </code></pre> });<p>&#x2F;&#x2F; It can also handle low-level actions<p>await agent.act(&#x27;Drag &quot;Use Magnitude&quot; to the top of the in progress column&#x27;);<p>&#x2F;&#x2F; Intelligently extract data based on the DOM content matching a provided zod schema<p>const tasks = await agent.extract(<p><pre><code> &#x27;List in progress issues&#x27;, z.array(z.object({ title: z.string(), description: z.string(), &#x2F;&#x2F; Agent can extract existing data or new insights difficulty: z.number().describe(&#x27;Rate the difficulty between 1-5&#x27;) })), </code></pre> );<p>```<p>We have a setup script that makes it trivial to get started with an example, just run &quot;npx create-magnitude-app&quot;. We’d love to hear what you think!<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;magnitudedev&#x2F;magnitude">https:&#x2F;&#x2F;github.com&#x2F;magnitudedev&#x2F;magnitude</a>
