Active Admin is a Ruby on Rails plugin for creating functional and good-looking back-end (administration) interfaces.

The interface is designed to be easy-to-use for non-technical users and flexible for developers.

By default, the plugin installs Devise, a widely-used authentication solution for Rails, in order to handle system users.

It can display data in different views (like grid, table, block or blog)  that can be paginated or filtered and every data displayed can be exported as XML, JSON or CVS.

Forms can be created and customized very quickly, thanks to the nice DSL created by Formtastic.

And, it is possible to design every page in many ways like using multiple grids, sidebar sections and more.
