RefineryCMS is an open source Ruby on Rails content management system. RefineryCMS development began as a closed source project at Resolve Digital in 2004, but in 2009 it was released as open source software under the MIT License. It has quickly become the most popular Ruby on Rails CMS with more than 100 contributors extending the application with engines and themes. Thanks to excellent internationalization support the interface has been translated into over 19 languages. Out of the box features include WYSIWYG content editing, image and file management and excellent SEO support.

Wordpress is a cross platform open source content management system (CMS) often used as a Blog publishing application. It is written in the PHP programming language with a MySQL database backend. Wordpress has a 'plugin' architecture that enables users and developers to substantially extend its functionality beyond the features that come with the base install.
