By Hongli Lai on August 19th, 2013

Phusion Passenger is a fast and robust web server and application server for Ruby, Python and Node.js. It works by integrating into Apache and Nginx and turning them into a fully-featured application server. It has high-profile users such as New York Times, AirBnB, Symantec, Pixar, etc, and comes with many features that make your life easier and your application perform better.

Phusion Passenger is under constant maintenance and development. Version 4.0.14 is a bugfix releases.

Phusion Passenger also has an Enterprise version which comes with a wide array of additional features. By buying Phusion Passenger Enterprise you will directly sponsor the development of the open source version.
