Radiant CMS - smart simplicity

Radiant CMS is a simple, open source content management system built on Ruby on Rails. It provides a file system-like hierarchy for organizing content into pages and page parts. Radiant CMS is page-centric and allows for custom layouts, behaviors, tags, and plugins. While not intended for large enterprise sites, it is well suited for blogs, portfolios, and other content-driven sites where simplicity and flexibility are priorities over extensive out-of-the-box features.
