Active Admin

Active Admin is a Ruby on Rails framework for creating elegant backends for website administration.

State of the project


We're currently working on 1.0.0, which as far as dependencies, moves us from meta_search to Ransack and adds Rails 4 & 5 support.

You can get it by tracking master:

gem 'activeadmin', github: 'activeadmin'

Or you can using rubygems:

gem 'activeadmin', '~> 1.0.0.pre4'

Keep in mind that during the time where we use pre-release label, things can break in each release!

Rails 5

Active Admin master has preliminary support for Rails 5. To give it a try, these Gemfile changes may be needed:

gem 'inherited_resources', github: 'activeadmin/inherited_resources'
gem 'ransack',             github: 'activerecord-hackery/ransack'
gem 'draper',              '> 3.x'
gem 'sass-rails',          github: 'rails/sass-rails' # For Sprockets 4

If something isn't working for you please report it on #4177.


The plan is to follow semantic versioning as of 1.0.0. The 0.6.x line will still be maintained, and we will backport bug fixes into future 0.6.x releases. If you don't want to have to wait for a release, you can track the branch instead:

gem 'activeadmin', github: 'activeadmin', branch: '0-6-stable'


Please note that is out of date. For the latest docs, check out the Github docs and the wiki.



  1. Enable developers to quickly create good-looking administration interfaces.
  2. Build a DSL for developers and an interface for businesses.
  3. Ensure that developers can easily customize every nook and cranny.

We try not to reinvent the wheel, so Active Admin is built with other open source projects:

Tool Description
Arbre Ruby -> HTML, just like that.
Devise Powerful, extensible user authentication
Formtastic A Rails form builder plugin with semantically rich and accessible markup
Inherited Resources Simplifies controllers with pre-built RESTful controller actions
Kaminari Elegant pagination for any sort of collection
Ransack Provides a simple search API to query your data
