Cowboy vs Gunicorn: What are the differences?

What is Cowboy? Small, fast, modular HTTP server written in Erlang. 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.

What is Gunicorn? A Python WSGI HTTP Server for UNIX. Gunicorn is a pre-fork worker model ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resources, and fairly speedy.

Cowboy and Gunicorn belong to "Web Servers" category of the tech stack.

"Websockets integration" is the primary reason why developers consider Cowboy over the competitors, whereas "Python" was stated as the key factor in picking Gunicorn.

Cowboy and Gunicorn are both open source tools. It seems that Gunicorn with 5.96K GitHub stars and 1.12K forks on GitHub has more adoption than Cowboy with 5.59K GitHub stars and 999 GitHub forks.
