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.
Phusion Passenger supports Ruby, Python, Node.js and Meteor.
There is a free and open source edition available.
Key Features
- User friendly.
- Reliable and secure – designed with security and stability in mind. Passenger defends against slow client attacks and common HTTP parser exploits, and uses privilege separation to keep intruders contained. Inspect or modify code on the fly by attaching a live IRB console, Ruby debugger, or low-level GDB to your running app. Passenger quietly restarts applications that crash, hang, or leak memory. Application updates don’t interrupt the service, and error resistance stops flawed updates.
- Fast, Efficient & Scalable – uses C++ to leverage the bare metal of your servers as much as possible for maximum efficiency and performance. Passenger also supports evented I/O for maximum scalability.
