How do Cloudflare Workers compare to Lambda@Edge?

Cloudflare Workers start in under 1ms with no cold start penalty, while Lambda@Edge cold starts can take hundreds of milliseconds. Workers run at 300+ PoPs versus Lambda@Edge's ~80+ AWS edge locations. Lambda@Edge supports Node.js and Python natively; Workers support JavaScript, TypeScript, Rust via WASM. Workers pricing is significantly lower for most use cases.

Can Fastly Compute@Edge replace Lambda@Edge for high-performance use cases?

Yes. Fastly Compute@Edge runs WebAssembly modules compiled from Rust, Go, Swift, or JS with deterministic sub-millisecond performance. It's particularly suited for request routing, auth token validation, and edge-side includes where consistent latency matters more than runtime breadth.

What limitations should I know about Lambda@Edge alternatives?

Edge compute platforms have execution time limits (typically 5–50ms per request), memory constraints, limited filesystem access, and restrictions on egress connections. Cloudflare Workers has 128MB memory and 30s CPU time on paid plans. Always verify the edge runtime supports your required APIs before migrating from Lambda@Edge.
