This RoR CMS can manage all types of website content. Don’t let the spelling error of their name put you off, as this is a very good quality developer asset with plenty of room for customisation. Although it also caters for non-coders through supplying a series of themes, custom fields widgets and ‘short code’, we still think you should have basic HTML knowledge to take full advantage of this very good Ruby on Rails website content manager. You can add multiple permissions for multiple user types, and this application isn’t overrun by low-quality open-source plugins, either. Very solid.
