Run WebAssembly at the edge on Fastly's global CDN with sub-millisecond cold starts and a Viceroy local dev environment.
Fastly Compute is an edge computing platform that executes WebAssembly modules across Fastly's global network, with cold-start latency consistently under 100 microseconds. Developers write handlers in Rust, JavaScript, Go, or any WASI-compatible language and deploy them with the Fastly CLI. The platform provides a local development environment called Viceroy that runs the exact same Wasm runtime as production, eliminating environment drift. Fastly Compute is used in production for edge-side request routing, authentication, A/B testing, and response transformation.
A serverless platform running on V8 isolates across 300+ global edge locations with native WebAssembly module support.
An open-source framework for building and running event-driven serverless applications using WebAssembly.
A CNCF project for building distributed applications from WebAssembly components using a capability-based actor model.
