Cowboy is a small, fast, and modern HTTP server written in Erlang. It is designed to handle large numbers of concurrent connections with minimal resource usage, making it well-suited for high-traffic web applications and APIs. Cowboy supports HTTP/1.1, HTTP/2, and WebSocket protocols out of the box.

Maintained by Loïc Hoguin and the Nine Nines project, Cowboy is widely used in the Erlang/Elixir ecosystem, often serving as the underlying web server for frameworks like Phoenix. Its lightweight architecture and OTP integration make it a popular choice for building real-time and distributed web services.
