For the last 5 years, active_admin and administrate have been the 2 default admin "frameworks" that were present in most commercial projects that I worked with. They felt legacy since day 1 of implementing them, but there was nothing better (faster, cheaper) on the market.
I had the (horrible) experience building complex UIs with active_admin, adding Hotwire to it... 😭
Well, now AVO is my default go-to admin in Rails. It has a nice UI, no technical debt and does not use any legacy technology (looking at you jQuery).
So yeah, I've come here to say thanks to Adrian and the dev team! ;)
