Active Admin vs. Redsmin vs. Massive

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

Redsmin is an all-in-one GUI for Redis, a tightly crafted developer oriented, online real-time monitoring and administration service for Redis.

Massive's goal is to help you get data from your database. This is not an ORM, it's a bit more than a query tool - our goal is to do just enough, then get out of your way. Massive embraces SQL completely, and helps you out when you don't feel like writing another mundane select * from statement.
