Phusion Passenger (informally also known as mod_rails and mod_rack among the Ruby community) is a free web server and application server with support for Ruby, Python and Node.js. It is designed to integrate into the Apache HTTP Server or the nginx web server, but also has a mode for running standalone without an external web server.[3] Phusion Passenger supports Unix-like operating systems, and is available as a gem package, as a tarball, or as native Linux packages.
