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. Your actual latency: 4 ms Test again 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. For a 50ms Worker compute workload including API Gateway & other required services 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.
