I've been working on this for some time now, starting with vm2, then deno-core for 2 years, and recently rewrote it on rusty_v8 with Claude's help. OpenWorkers lets you run untrusted JS in V8 isolates on your own infrastructure. Same DX as Cloudflare Workers, no vendor lock-in. What works today: fetch, KV, Postgres bindings, S3/R2, cron scheduling, crypto.subtle. Self-hosting is a single docker-compose file + Postgres. Would love feedback on the architecture and what feature you'd want next.

hi hn, i built openwork, an open-source, local-first system inspired by claude cowork. it’s a native desktop app that runs on top of opencode (opencode.ai). it’s basically an alternative gui for opencode, which (at least until now) has been more focused on technical folks. the original seed for openwork was simple: i have a home server, and i wanted my wife and i to be able to run privileged workflows. things like controlling home assistant, or deploying custom web apps (e.g. our customs recipe app recipes.benjaminshafii.com), legal torrents, without living in a terminal. our initial setup…

I've been working with a partner team to integrate wasm workloads with existing container toolchains with the goal of enabling wasm workloads anywhere, be it on the edge, in kubernetes, or wherever. To that end, this project implements a containerd shim which runs those wasm workloads. It is designed as a library to bring your own host implementation, but also includes an implementation for WASI. Right now the library assumes you are using wasmtime, which is embedded in. It works either standalone (run with containerd directly) or in kubernetes. Kubernetes networking and storage are wired…

QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM. If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code. QuickBEAM runs that JavaScript inside OTP supervision trees. Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.). This makes it usable for: - SSR…

For the last month or so I've been working on bewCloud, and today I'm making its source code public and open! Right now, the Dashboard (URLs + freeform notes), News (RSS/Atom/JSON feeds), and Contacts (CardDav) are working. If you have any suggestions, comments, or recommendations, I'd love to hear it. Thank you for your attention and kindness. I really appreciate it!

Hi HN! We’re Asankhaya and Rohan and we are building Patchwork. Patchwork tackles development gruntwork—like reviews, docs, linting, and security fixes—through customizable, code-first 'patchflows' using LLMs and modular code management steps, all in Python. Here's a quick overview video: https://youtu.be/MLyn6B3bFMU From our time building DevSecOps tools, we experienced first-hand the frustrations our users faced as they built complex delivery pipelines. Almost a third of developer time is spent on code management tasks[1], yet backlogs remain. Patchwork lets you combine…

I needed a way to let users write JavaScript to create plugins for a site I'm building. I couldn't find a solution I was happy with, so ended up building one that run's it in a web worker on a separate domain from your main site. Hopefully I haven't missed anything. If so, please let me know! My website has an interactive demo you can write code in the browser textarea, and see the output on the right.
