Introducing Phusion Passenger™

Phusion Passenger™ — a.k.a. mod_rails or mod_rack — makes deployment of Ruby web applications, such as those built on the revolutionary Ruby on Rails web framework, a breeze. It follows the usual Ruby on Rails conventions, such as “Don’t-Repeat-Yourself”.

• Deployment is only a matter of uploading application files. No Ruby (on Rails)-specific server configuration required!
• Built on the industry standard Apache web server.
• Allows Ruby on Rails applications to use about 33% less memory, when used in combination with Ruby Enterprise Edition (optional).
• Zero maintenance. No port management, server process monitoring or stale file cleanup required. Errors are automatically recovered whenever possible.
• Designed for performance, stability and security. Phusion Passenger should never crash Apache even in case of crashing Rails applications.
• Well-documented, for both system administrators and developers!
