Active Admin

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

Goals

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

Getting started

• Check out the docs.
• Try the live demo.
• The wiki includes links to tutorials, articles and sample projects.

For enterprise

Active Admin for enterprise is available via the Tidelift subscription. Learn More.

Need help?

Please use StackOverflow for help requests and how-to questions.

Please open GitHub issues for bugs and enhancements only, not general help requests. Please search previous issues (and Google and StackOverflow) before creating a new issue.

Google Groups, IRC #activeadmin and Gitter are not actively monitored.
