What is Cloudflare Workers?
Serverless compute platform running code at the edge across 300+ global locationsCloudflare Workers is a serverless compute platform that runs JavaScript, TypeScript, Python, Rust, and WebAssembly code at the edge across more than 300 data centers worldwide, providing sub-millisecond cold start times and eliminating the regional latency problems of traditional cloud functions. Unlike AWS Lambda or Google Cloud Functions that run in specific regions, Workers execute on the Cloudflare edge network, meaning code runs physically close to users everywhere in the world simultaneously. The platform includes Workers KV for globally distributed key-value storage, Durable Objects for strongly consistent stateful computing, R2 for S3-compatible object storage without egress fees, D1 for serverless SQLite databases, and Queues for reliable message processing. This ecosystem enables building complete applications entirely on the Cloudflare edge without managing any servers or traditional cloud infrastructure. Workers supports standard Web APIs and is compatible with many npm packages, and the Wrangler CLI provides a full local development environment with hot reloading.
