Merb, short for "Mongrel+Erb", is a model–view–controller web framework written in Ruby. Merb adopted an approach that focused on essential core functionality, leaving most functionality to plugins. Merb’s unofficial slogan was “No code is faster than no code,” a reflection of the philosophy that smaller software had the potential to be both more performant and simpler to debug. Merb was merged into Rails web framework on December 23, 2008 as part of the Ruby on Rails 3.0 release.
Merb 1.0 was released on November 7, 2008 at RubyConf. and is currently at version 1.1.
The Merb project was started as a "clean-room" implementation of the Ruby on Rails controller stack, but has grown to incorporate a number of ideas which deviated from Rails's spirit and methodology, most notably, component modularity, extensible API design, and vertical scalability. Most of these capabilities have since been incorporated back into Rails during the Rails/Merb merger announced on December 23, 2008.
