# Phusion Passenger: a fast and robust web server and application server for Ruby, Python and Node.js

[Phusion Passenger™](https://www.phusionpassenger.com/) 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. Phusion Passenger supports Ruby, Python, Node.js and Meteor, and is being used by high-profile companies such as **Apple, Pixar, New York Times, AirBnB, Juniper** etc as well as [over 350.000 websites](http://trends.builtwith.com/Web-Server/Phusion-Passenger).

What makes it so fast and reliable is its **C++** core, its **zero-copy** architecture, its **watchdog** system and its **hybrid** evented, multi-threaded and multi-process design.
