= Cowboy

Cowboy is a small, fast and modern HTTP server for Erlang/OTP.

== Goals

Cowboy aims to provide a complete HTTP stack in a small code base. It is optimized for low latency and low memory usage, in part because it uses binary strings.

Cowboy provides routing capabilities, selectively dispatching requests to handlers written in Erlang.

Because it uses Ranch for managing connections, Cowboy can easily be embedded in any other application.

Cowboy is clean and well tested Erlang code.
