What it is

Fastly Compute runs WebAssembly modules at the edge. Supports Rust, Go, JavaScript, AssemblyScript, and Python (via Wasm). Strong on programmability and performance — sub-millisecond execution. Enterprise-shaped pricing and procurement.

Best for

  • Enterprises with existing Fastly CDN procurement
  • Apps requiring Rust / Go performance at the edge
  • Multi-language teams that benefit from WASM as a runtime target

When not to pick it

Skip Fastly Compute for greenfield projects — pricing and procurement are enterprise-flavoured. Cloudflare Workers covers similar use cases with a more developer-friendly entry point.

My take

Fastly Compute is enterprise-grade WASM edge. For Fastly customers it is the natural extension. For everyone else, Cloudflare Workers is the more practical default.
