An open-source framework for building and running event-driven serverless applications using WebAssembly.
Fermyon Spin is the most developer-friendly framework for building Wasm-native serverless applications. Applications are defined as a set of Wasm components wired together by a spin.toml manifest, with built-in triggers for HTTP, Redis pub/sub, and scheduled jobs. Spin provides managed access to key-value stores, SQL databases, and outbound HTTP — all governed by the WASI capability model. The same Spin application runs locally with spin up, on Fermyon Cloud, on Kubernetes via SpinKube, or on any Wasmtime-based runtime, with no code changes.
