Gunicorn vs Passenger: What are the differences?

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; Passenger: 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.

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

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

Gunicorn and Passenger are both open source tools. It seems that Gunicorn with 5.91K GitHub stars and 1.12K forks on GitHub has more adoption than Passenger with 4.4K GitHub stars and 506 GitHub forks.

Movielala, DSTLD, and Fab are some of the popular companies that use Passenger, whereas Gunicorn is used by reddit, hike, and OpenLabel. Passenger has a broader approval, being mentioned in 372 company stacks & 41 developers stacks; compared to Gunicorn, which is listed in 184 company stacks and 50 developer stacks.
