Welcome! Use this Playground to test drive a Worker, create a demo to share online, and when ready deploy directly to the edge by setting up a Cloudflare account.

What is a Worker?

A Cloudflare Worker is JavaScript code you write that handles your web site's HTTP traffic directly in Cloudflare's edge locations around the world, allowing you to locate code close to your end users in order to respond to them more quickly

Try it yourself

On your left is a sample Worker that is running on this site. You can edit it live and see the results here. Edit the path above to /api to see how the example Worker handles different routes. You can also edit the code to see what's possible and bring your next idea to life.
