Radiant is billed as a no-fluff, fairly friendly, easy to use and customize open source Content Management System (CMS). It is similar to Textpattern or MovableType, but is a general purpose content management system (not just a blogging engine).
Radiant is limited to basic functionality for a CMS. The intended users are small groups or teams and therefore the software leaves room for extensions. All of the content is stored inside a database (either MySQL, PostgreSQL or SQLite).
Radiant depends, like every Ruby on Rails application, on the installed adapters for the database.
Features include:
- An elegant user interface.
- Flexible templating with layouts, snippets, page parts, and a custom tagging language.
- Extension/plugin system.
- Simple user management and permissions.
- Simple admin interface centering around three key components: pages, snippets and layouts.
- Support for Markdown and Textile as well as traditional HTML.
- Custom text filters.
- Intelligent page caching which expires pages every 5 minutes.
- Built using Ruby on Rails.
