Serve is a small Rack-based web server and rapid prototyping framework for Web applications (specifically Rails apps). Serve is meant to be a lightweight version of the Views part of the Rails MVC. This makes Serve an ideal framework for prototyping Rails applications or creating simple websites. Serve has full support for Rails-style partials and layouts.
