  • 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.
