Seed: A New Rails Powered Open Source CMS With In-Page Admin Interface

The Media Collective’s “common sense CMS” named Seed (code) (demo) (screencast) is a diamond in the rough. It supports Akismet spam blocking, monitoring via New Relic, media storage via Amazon’s S3, page caching, and fine-grain control of page editing on a per-user basis – all out of the box. It joins existing Rails CMS’s like Refinery and Radiant, but comes better styled at the start than either of the two and the live on-page administration interface sets it apart. Seed is also MIT licensed so you can use it in your own projects without any hassles.
