Cowboy

Cowboy is a small, fast and modular HTTP server written in Erlang.

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.

No parameterized module. No process dictionary. Clean Erlang code.

Sponsors

The SPDY implementation was sponsored by LeoFS Cloud Storage.

The project is currently sponsored by Kato.im.
