A serverless platform running on V8 isolates across 300+ global edge locations with native WebAssembly module support.
Cloudflare Workers executes JavaScript and WebAssembly across Cloudflare's network of 300+ edge locations, with response times typically under 5 ms globally. Workers written in JavaScript or TypeScript can import and instantiate Wasm modules directly, making it straightforward to run computationally intensive logic — image processing, cryptography, ML inference — at the same edge node that handles the HTTP request. The workers-rs crate enables writing Workers entirely in Rust, compiled to Wasm. Cloudflare's internal infrastructure — including R2, D1, and Durable Objects — is itself built on Wasm.
