Ramaze
From DocForge
Ramaze is an open source web application framework written in Ruby.
Ramaze doesn't introduce any major change of paradigm for everyone familiar with Ruby and the basics of web development.
Ramaze tries to be intuitive and easy to learn. Most functionality is built in a way to help, not to obfuscate or confuse.
Even the most essential parts of Ramaze can easily be replaced and/or modified without losing the advantage of the whole framework.
