Cloudflare Workers® This app works best with JavaScript enabled. You write code.
We handle the rest.
Deploy serverless code instantly across the globe to give it exceptional performance, reliability, and scale.
From signup to globally deployed in <5min Your code runs within milliseconds of your users worldwide Say goodbye to cold starts—support for 0ms worldwide ~/ $ npm create cloudflare -- my-app~/ $ cd my-app~/my-app $ npx wrangler deployPublished https://my-app.world.workers.dev
Laurie Voss
Co-founder & Chief Data Officer
NPM Logo for the company NPM “Cloudflare Workers has changed the way we build our apps. We don’t have to think about regions, we just deploy code and it runs seamlessly around the world.”
Great power.
Less responsibility.
Automatic scaling No more configuring auto-scaling, load balancers, or paying for capacity you don’t use. Traffic is automatically routed and load balanced across thousands of servers. Sleep well as your code scales effortlessly.
High performance global network Every deploy is made to a network of data centers running V8 isolates . Your code is powered by Cloudflare’s network which is milliseconds away from virtually every Internet user.
Write in JS, Rust, C, and C++ Choose from a template in your language to kickstart building an app, creating a function, or writing an API. We have
templates ,
tutorials , and a
CLI to get you up and running in no time.
Support for 0ms cold starts Most serverless platforms experience a cold start every time you deploy or your service increases in popularity. Workers can run your code instantly, without cold starts.
Exceptionally affordable The first 100,000 requests each day are free and paid plans start at just $5/10 million requests, making Workers as much as ten-times less expensive than other serverless platforms.
No servers to maintain Spend more time building, less time configuring. No VMs, no servers, and no containers to spin up or manage. Deploy using our CLI, web interface, or API.
Edge storage, built in Store your static assets at the edge with Workers KV, our global, low-latency key-value data store. Access your assets alongside your code and transform them via powerful APIs (e.g. HTMLrewriter) to modify your page before it reaches the user.
Static assets with dynamic power Say goodbye to build steps which pre-generate thousands of assets in advance. Harness the unrivaled raw power of the edge to generate images, SVGs, PDFs, whatever you need, on the fly , and deliver them to users as quickly as a static asset.
Build your first Worker now. Deploy up to 100 Worker scripts Runs on all 275+ network locations Free workers.dev subdomain Up to 10ms CPU time per request Lowest latency after the first request Limited Workers KV edge storage Everything in Free, plus: Up to 30s of CPU time per request Always lowest latency Additional Workers KV edge storage
