About Cloudflare Workers

Cloudflare Workers is a serverless computing platform that executes JavaScript, TypeScript, and Rust code across Cloudflare’s global edge network. Designed for developers seeking to minimize latency, it leverages V8 isolates to achieve near-instantaneous cold starts compared to traditional container-based serverless functions. By running logic closer to end-users, it enables high-performance web applications, dynamic content generation, and API acceleration. This platform is ideal for teams building distributed systems that require massive scalability and low-latency execution without the overhead of managing underlying infrastructure or server provisioning.
