I have been using the pretty looking active admin recently and ran in to some issues happening across my application with a performance issue and other things including the taking over of the clean and nice "search" keyword used by the Sunspot gem (like Model.search) which is replaced by the meta_search.
So I am now unhappy with ActiveAdmin and would like to see if there are some nice alternatives out there that can give a good administration framework as well as give the ability to browse data, since I will be deploying on heroku and browsing the database directly there without something like active_admin is not that simple.
Any suggestions or pointers to admin frameworks will be much appreciated

To my surprise I noticed that the first gem I used for this purpose is still actively being developed: activescaffold
Also for future reference check the ruby-toolbox's relevant category .
