MODX is a free, open source content management system and Application Framework. It is written with the PHP programming language and uses the popular MySQL database.
MODX provides a powerful framework on which to deploy and secure websites and web applications. For example, it provides a true system for registered web users and groups that is separate from administration users.
You can grant some web users access to one page and others access to another page. For content management, you can easily duplicate documents, folders, chunks and snippets. Most significant, though, is MODX’s ability to empower users to quickly and easily create and maintain a rich and dynamic website.
