nghttp2 is a mature C library implementing the HTTP/2 framing layer and HPACK header compression, plus client, server, proxy, and load-testing tools built on top. It also supports HTTP/3/QUIC in its proxy and benchmarking tools and is widely used as the HTTP/2 implementation in other software.
Use cases
- implement http/2 protocol support in a c or c++ application
- encode and decode hpack header compression
- run a reverse proxy that speaks http/2 and http/3
- load test and benchmark an http/2 server
- test http/2 client behavior against a reference server
When to choose
- you need a battle-tested, spec-compliant HTTP/2 framing library in C
- you want HPACK encoder/decoder as a public API
- you need HTTP/2 or HTTP/3 load testing with h2load
- you want a high-performance reverse proxy with HTTP/3 support
When to avoid
- you only need a high-level HTTP client in a scripting language
- you want a full-featured application web server rather than a protocol library
- your project cannot link native C libraries
