Rails Admin

RailsAdmin is a mountable admin backend for Ruby on Rails that generates polished CRUD interfaces for your Active Record models. It automatically infers fields, associations, and validations, giving you searchable, sortable list views and rich edit forms with very little setup. The engine supports custom actions, batch operations, and export flows so non-developer staff can manage content and data safely. It integrates with popular authentication and authorization systems (e.g., Devise for login, Pundit/CanCanCan for permissions), and plays nicely with file uploads via Active Storage and common upload gems. Configuration is declarative: you tailor fields, labels, filters, and navigation structure in a single place without forking templates. For many Rails apps, RailsAdmin provides a production-ready back office that saves weeks of bespoke tooling while remaining easy to extend when business rules get more complex.
