I'd say that the classic direct competition are Active Admin, Administrate, rails admin. They are the OG admin panel builders in the Rails world. They focus a lot on building just classic CRUD admin panels.

I focused on making Avo a whole app development platform. It's not that hidden place where just a few team members go to update some records, but the actual UI that you give to your users.

I'll make sure to create an "alternatives" page with competitors.
