Cloudflare Workers execute JavaScript/TypeScript/WASM at the network edge — 300+ data centers worldwide. Requests hit the nearest edge location for sub-10ms latency. Use cases: API proxying, A/B testing, authentication, redirects, image optimization, and full applications. Free tier: 100K requests/day. Workers are the serverless platform with the lowest cold-start time (0ms — code is always warm).
