Wasm Workers Server: Portable Serverless Apps with WebAssembly
summary
Wasm Workers Server (wws) is an open source CLI that runs portable serverless apps compiled to WebAssembly and also supports interpreted files (JavaScript, Python, Ruby) by embedding interpreters; examples show Rust, Go, JS and Python working together. It routes requests to independent workers, passes data via STDIN/STDOUT serialization, enforces per-worker permissions, and provides an in-memory KV, external HTTP, dynamic and catch-all routing, static assets and AI inference integration. Deployment runs locally, in containers, on Raspberry Pi or cloud; current tradeoff is added latency from cross-boundary serialization.
