ActiveAdmin is a Ruby on Rails plugin for generating administration style interfaces. I have used it for a number of applications. Thoughtbot has announced the release of Administrate.

Administrate wins over me because of the following reasons:

  1. No DSLs.
  2. Let developers override defaults in a conventional way – with common Rails controllers and views.
  3. Break up the library into core components and plugins, so each component stays small and easy to maintain.
  4. A cleaner and better design by far

I think Administrate is awesome and I might be using this for my current project!
