“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.”
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++
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.
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
