Passenger 6 has arrived
Passenger 6 introduces standardization across your stack by supporting all languages.
Supercharge Your Web App
Passenger has a myriad of features that are invaluable to today’s web apps and microservice APIs. You get these benefits (and more) by simply installing Passenger with Nginx or Apache. Learn how.
Optimization
Passenger was built with high performance and efficiency in mind. With Passenger’s zero-copy architecture, turbocaching and support for multiple concurrency models, you can count on Passenger to get the most out of your hardware.
Stability
Passenger auto-manages your apps’ processes, restarting them and itself if they ever crash. Passenger also keeps resource hogging apps in check, giving your web app maximum uptime.
Documentation
A tool is only as good as its users are able to wield it. Passenger comes with world class documentation to allow you to fully leverage its features.
Security
Passenger protects your web apps from various malicious attacks like slow client attacks, common HTTP parser exploits and privilege escalations.
Reliability
Passenger was battle-tested with some of the most demanding web apps for over a decade. This makes it one of the toughest app servers to date, currently powering over 650,000 web apps.

As a consultant, I'm less likely to have anything to fix with Passenger, compared to other Ruby deploys. So many botched setups in the wild.
