Cloudflare Workers
Run serverless code with exceptional performance, reliability, and scale.
Build serverless functions and applications without configuring or maintaining infrastructure with global deployment to over 335 data centers around the world on Cloudflare’s global network.
BENEFITS OF WORKERS
Increase developer productivity
Deploy to Workers directly from any Git repository and spin up applications in hours not days without additional tooling.
Scale automatically
No action is required from developers to add more compute power or worry about reaching a limit no matter how much traffic an application receives.
Improve performance and reliability
Gradually deploy code to an optimal location automatically to improve performance and reliability.
Run serverless code from region: Earth
To enable industry-leading performance automatically, Cloudflare Workers runs on V8 isolates not containers. Our V8 isolate architecture enables instant start up times at no additional cost as there is no delay waiting for the runtime to be loaded into an instance upon initiation. Isolates already have the runtime, all that is needed is for the code to be loaded on invocation, virtually eliminating cold starts on requests.

What our customers are saying
We need exceptionally strong security for our customers who upload private app code to Docker Hub. Cloudflare Workers provides an authentication layer that ensures that anyone who tries to access user data is authorized to do so.

Top Workers use cases
Focus on your code and innovate faster.
Run serverless functions
From fast and light to longer running and more CPU-intensive workloads, deploy and execute code globally.
Build frontend applications
Upload and serve HTML, CSS and client-side JS with native support for static files with React Router, OpenNext, or the Vite plugin.
Proxy and cache third-party APIs
Use Workers to fetch data from 3rd party services, transform responses, and cache them at the edge to reduce latency and API costs.
