H2O is a high-performance open-source web server that supports HTTP/1.x, HTTP/2, and HTTP/3. Written in C, it focuses on reducing page load times by making active use of HTTP/2 features such as server push and prioritization; configuration is written in YAML, and request-handling logic can be extended with mruby. It can be used not only as a standalone server but also as an embeddable library.
