A lightweight CMS toolkit for Ruby on Rails, based on Bootstrap

Casein is a Rails gem that provides scaffolding generators and helper functions to quickly create a clean and minimal CRUD interface for your data.

It comes with a pre-rolled user-authentication system, supports user-based timezones, and is mobile-ready.

As Casein is completely decoupled from the front end, it can be added to new or existing Rails projects, or used as a standalone CMS to drive platforms built on other technologies.
