About Cloudflare Workers
Cloudflare Workers provides a serverless compute service built on Google's V8 JavaScript engine, allowing developers to deploy JavaScript, Rust, C, and C++ code across the globe. By leveraging Cloudflare's edge network, applications experience reduced latency and improved performance. It supports a wide range of use cases, including API endpoints, website logic modifications, image manipulation, A/B testing, and authentication. The platform deeply integrates with other Cloudflare products like Workers KV, R2 object storage, and the D1 serverless SQL database, providing a comprehensive stack for building full-stack applications without traditional server management.
