- Kyushu is an open source CLI for running JavaScript/TypeScript handlers as Wasm binaries.
- It allows building handlers into self-contained WebAssembly binaries for execution anywhere.
- Runs without Node.js, Bun, or Docker, using only a single binary command.
- Features a Cloudflare Workers-style API, including a familiar fetch handler.
- It is self-hostable on VPS or any environment, with WebAssembly sandbox isolation from the host.
