Cloudflare Worker

Deploy serverless code instantly across Cloudflare’s global network of 330+ data centers using V8 isolates for zero-cold-start performance.

Cloudflare Workers move logic to the edge, executing JavaScript, Rust, or Python within milliseconds of your users. By ditching traditional containers for V8 isolates, the platform eliminates cold starts and reduces overhead (memory limits typically sit at 128MB). You get built-in integration with KV storage, R2 object storage, and D1 SQL databases. It is the standard for building high-performance APIs, HTML rewriters, and full-stack applications that scale automatically without managing a single server or region.
