***The top 5 gems are listed below :***

 1. Active Admin

 2. Devise

 3. Rspec

 4. CanCanCan

 5. Pry

It makes the building of the admin panel very simple and doesn’t require too much effort or configurations. Moreover, it comes with a number of features by default, but it also allows the user to modify the entire thing.
