Regulate is a Rails 3 engine that provides a Git backed CMS that allows for an admin to define editable regions in a page view.
We often have applications that need fairly basic CMS solutions but the client may not have someone on staff that knows HTML. We needed a CMS that wasn't bloated, lived as an engine, allowed us to regulate what parts of a page could be editable, and we wanted it to be Git backed so we could have version control over the edits. We also designed regulate to work with any authentication / authorization service thanks to Ryan's abstract_auth gem.
To get a quick idea of what Regulate is all about watch the video below.
