Cloudflare Workers run serverless code at the edge across 330+ data centers worldwide. Unlike traditional serverless (AWS Lambda), Workers have near-zero cold starts because they use V8 isolates rather than container-based execution.
The platform supports JavaScript, TypeScript, Rust, and WebAssembly. Complementary services include Workers KV for global key-value storage, Durable Objects for stateful coordination, R2 for S3-compatible object storage, D1 for SQLite databases, and Queues for async message processing.
Workers AI brings model inference to the edge, enabling AI-powered applications without managing GPU infrastructure. The Wrangler CLI provides local development, testing, and deployment workflows.
Free tier includes 100K requests per day. Paid plans start at $5/month for 10M requests. Enterprise plans offer custom limits, SLAs, and dedicated support.
