Oxy is Cloudflare's Rust-based next generation proxy framework

This post introduces Oxy, a new Rust-based proxy framework that serves as a foundation for several Cloudflare projects, including the Zero Trust Gateway and iCloud Private Relay's second hop proxy. Oxy enhances Cloudflare's edge computing capabilities by providing a programmable, highly customizable, and extensible proxy server that can handle massive amounts of traffic. It allows engineers to control every aspect of proxying, from protocol decapsulation to DNS resolution, and integrates with surrounding infrastructure for telemetry and networking services. Its extensibility model is similar to Cloudflare Workers, enabling developers to build sophisticated applications with minimal code.
