Build serverless applications and deploy instantly across the globe for exceptional performance, reliability, and scale.

Cloudflare Workers provides a serverless execution environment that allows you to create new applications or augment existing ones without configuring or maintaining infrastructure.
Cloudflare Workers runs on Cloudflare’s global network in over 200 cities around the world, offering both Free and Paid plans.
Bindings allow your Workers to interact with resources on the Cloudflare developer platform, including R2, KV, Durable Objects, and D1.
The Playground is a sandbox which gives you an instant way to preview and test a Workers script directly in the browser against any site. No setup required.
