Lwan vs Passenger: What are the differences?

Developers describe Lwan 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. On the other hand, Passenger is detailed as "A fast and robust web server and application server for Ruby, Python and Node.js". Phusion Passenger is a web server and application server, designed to be fast, robust and lightweight. It takes a lot of complexity out of deploying web apps, adds powerful enterprise-grade features that are useful in production, and makes administration much easier and less complex.

Lwan and Passenger can be categorized as "Web Servers" tools.

Lwan and Passenger are both open source tools. Lwan with 5.01K GitHub stars and 524 forks on GitHub appears to be more popular than Passenger with 4.41K GitHub stars and 505 GitHub forks.
