Active Admin vs Massive: What are the differences?
Developers describe Active Admin as "The administration framework for Ruby on Rails applications". Active Admin is a Ruby on Rails framework for creating elegant backends for website administration. On the other hand, Massive is detailed as "A Postgres-Centric Data Access Tool". 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.
Active Admin and Massive can be primarily classified as "Database" tools.
Active Admin and Massive are both open source tools. It seems that Active Admin with 8.51K GitHub stars and 3.01K forks on GitHub has more adoption than Massive with 2.55K GitHub stars and 194 GitHub forks.
