Cowboy vs Lwan: What are the differences?
Developers describe Cowboy as "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. On the other hand, Lwan is detailed as "Experimental, scalable, high performance HTTP server". In development for almost 3 years, Lwan was until now a personal research effort that focused mostly on building a solid infrastructure for a lightweight and speedy web server.
Cowboy and Lwan can be categorized as "Web Servers" tools.
Cowboy and Lwan are both open source tools. It seems that Cowboy with 5.59K GitHub stars and 999 forks on GitHub has more adoption than Lwan with 5.01K GitHub stars and 524 GitHub forks.
