Products that do what Building a Rust-ish programming language with 100% coding agents: Wado does

I started this in January and haven't written a line of the compiler myself. Coding agents write every line; I do design and taste. Wado is a Rust-flavored, GC'd language for WebAssembly Component Model. Try it in the browser, and ask me anything!

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    Hi HN, I recently open sourced a small tool (Remuda) that I built at work to remove some of the friction of launching and managing agents and figured HN might be interested. I also wrote a post on the company blog that goes into more detail about why I built it and showcases its features: https://www.yendo.com/blog/remuda-an-agent-orchestrator

    After 6 years of coding almost every day, I'm finally ready to show HN. There's a lot going on here, looking forward to your guy's feedback.

    I’ve had this idea for a new code editor chord grammar bouncing around in my head for over 2 years, and now I can finally release v0.1 of ane. You can run it one-shot from scripts or agents (`ane exec —chord…`) or use its full-on TUI editor. ane is pure Rust, and integrates tree-sitter and LSP to provide a pleasant and predictable terminal code editing experience. I’d love folks to try it out and give feedback! Thanks :)

    Hi HN, While building RAG agents, I noticed a lot of token budget was wasted on formatting overhead (HTML tags, JSON structure, whitespace). Existing solutions felt too heavy (often requiring torch&#x2F;transformers), so I wrote this lightweight, zero-dependency library to solve it. It includes strategies for context packing, PII redaction, and tool output compression. Benchmarks show it can save ~15% of tokens with negligible latency overhead (<0.5ms). Happy to answer any questions!

    Release 1.8.2 of wazero, the zero dependency WebAssembly runtime for Go, brings the amd64 compiler to 4 new OSes: NetBSD, DragonFly BSD, illumos and Solaris. The compiler also supports Linux, FreeBSD, macOS and Windows, on amd64 and arm64. This didn't require any changes to the compiler, just enabling it after setting up tests to validate that it already worked. Now the HN hook: noticeably absent is OpenBSD, which I failed to get working, even after taking W^X into account (we already had that for arm64 on macOS). If you wanna help, please drop us a note!

    Hi there, I built a React code editor component that also compiles, executes and returns the outputs of the program written in it (via pyodide&#x2F;webassembly). I believe that this is a useful package for those building projects with web-based code editors. Expanding the library to be more flexible + have greater language support is a goal for the future. Hope it helps someone out there - please feel free to reach out if I can assist. Feedback and suggestions are always welcome.

    Hey HN, I made a code editor which is inspired by Xi-editor. It's native GUI and GPU rendered written in Rust. A main feature is remote development support (VSCode like). Also other features like Vim-like modal editing, Tree-sitter for syntax highlighting, built-in LSP support and WASI based plugin system.

    I’ve found coding agents to be great at 1&#x2F; finding everything they need across large codebases using only bash commands (grep, glob, ls, etc.) and 2&#x2F; building new things based on their findings (duh). What if, instead of a codebase, the files were all your workplace docs? There was a `Google_Drive` folder, a `Linear` folder, a `Slack` folder, and so on. Over the last week, we put together Craft to test this out. It’s an interface to a coding agent (OpenCode for model flexibility) running on a virtual machine with: 1. your company's complete knowledge base represented as…

    We are a small group of undergrads interested in building human in the loop coding agents. We dream of a world where building complex agent workflows feels as simple and creative as playing with legos. When we were building stuff we needed a tool that made it easy to try out different code embedding models so that we could see which ones worked best in different scenarios and understand their strengths and weaknesses. So to speed that process up we made PurpleSearch an 'instant' search engine for your local codebases. This tool lets you quickly deploy any open source embedding model on…

    Hi HN! We (pdubroy & marianoguerra) just launched an online book called WebAssembly from the Ground Up. It's an online book to learn Wasm by building a simple compiler in JavaScript. This is the book we wish we'd had 3 years ago. Unlike many WebAssembly resources that focus on use cases and tooling, we wanted a deep dive into how Wasm actually works. We focus on the core of WebAssembly: the module format and the instruction set. We think the low-level details — the "virtual ISA" — are the most interesting part, and we had the crazy idea that writing a compiler is the best way to learn it.…

    Hi everyone, After four years, I'm finally open sourcing my little markup language that compiles directly to HTML, and has all the "modern" features built into the core, (reactive components, server side rendering, modules, bundling, etc.). No metaframework required! Feels like I really have something here, I'd love your feedback :)

    Recently several AI labs have published experiments where they tried to get AI coding agents to complete large software projects. - Cursor attempted to make a browser from scratch: https:&#x2F;&#x2F;cursor.com&#x2F;blog&#x2F;scaling-agents - Anthropic attempted to make a C Compiler: https:&#x2F;&#x2F;www.anthropic.com&#x2F;engineering&#x2F;building-c-compiler A few weeks ago I posted xmloxide, an agent-made Rust replacement for libxml2 made by pointing Claude code at the libxml2 test suite: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=47201816 curl is arguably the most widely deployed…

    Hi HN! I've never posted anything on here before, but this project was too fun to pass up. I've been learning a lot about agents lately, and wanted to see if I could replicate some of the results of Windsurf and Cursor. Generally I love these tools, but when you're stuck behind an "enterprise" firewall, they don't work as well. This sad state of affairs motivated me to understand SWE agents more. Does it work? Yes. Is it as good as Cursor and Windsurf? Not quite, but it's pretty darn close, depending on the model you use. I'm lacking a few features like semantic indexing, MCP support, but…
