About Cloudflare Workers

Cloudflare Workers lets you deploy JavaScript, TypeScript, and WASM code to Cloudflare's global network with zero cold starts.

Key Features

Zero cold starts
300+ edge locations
KV storage
R2 object storage
D1 SQLite
Free tier included

Cloudflare Workers execute code at the edge — in over 300 data centers worldwide — with virtually zero cold start latency. Unlike traditional serverless platforms that run in specific regions, Workers run close to the user no matter where they are. The platform supports JavaScript, TypeScript, Rust (via WASM), and Python. Combined with companion products like KV (key-value storage), R2 (S3-compatible object storage), D1 (SQLite at the edge), and Durable Objects (stateful coordination), Workers can power entire applications without a traditional server. The free tier includes 100,000 requests per day.
