Proxygen is Facebook's collection of C++ HTTP libraries, providing core HTTP abstractions and an easy-to-use HTTPServer framework. It supports HTTP/1.1, HTTP/2, and HTTP/3 and is used as the basis for building HTTP servers, proxies, and clients.

Use cases

• build a high-performance HTTP server in C++
• implement an HTTP proxy in C++
• serve HTTP/2 or HTTP/3 traffic
• embed an HTTP server in a C++ application
• build custom HTTP clients and servers on common abstractions

When to choose

• you need a performant, modern C++ HTTP library with HTTP/2 and HTTP/3 support
• you are building servers, proxies, or clients at scale and want battle-tested Facebook infrastructure
• you want a simple HTTPServer framework on top of flexible low-level abstractions

When to avoid

• you want a quick high-level web framework with routing, templating, and batteries included
• your project is not C++ or you need minimal build complexity
• you need broad platform support beyond Linux and macOS without extra effort
