Rack is a modular interface between web servers and web applications developed in the Ruby programming language. With Rack, application programming interfaces (APIs) for web frameworks and middleware are wrapped into a single method call handling HTTP requests and responses.
Rack is used by many Ruby web frameworks and libraries, such as Ruby on Rails and Sinatra. It is available as a Ruby Gem. Many Ruby applications are called "rack-compliant".[2]
Rack has inspired similar frameworks in JavaScript[3] (jack.js), Clojure,[4] Perl (Plack), Common Lisp (Clack),[5] and .NET (OWIN).[6]
