Kyushu is a self-hostable Wasm sandbox for JavaScript workers. Think Cloudflare Workers, but on your own VPS. Write a JS fetch handler, ship it as a standalone binary, and run it on your server. Use cases could be running untrusted code safely, building edge-like handlers on your infra, or giving AI agents a sandboxed environment to execute logic. Open source. Early stage. Give it a try and upvote if you ❤️ it!
