I have mixed feelings.
I just switched to Django from Supabase/Firebase. The main thing I like is theirs a plugin for everything you’d want.
It’s also much easier to actually self host, Supabase is open source, but actually doesn’t self host all that well. You have a bizarre gap between ’free’ with constant nag emails warning you there about to turn off your project, a 25$ paid tier and a black box enterprise level. Call us isn’t very transparent.
For Plain, I’d much rather this be a Django plugin, I don’t want to replace a well supported and documented framework with a 1 person fork. Definitely looks cool, but you’ll never be able to provide the same ecosystem and support as the main Django project.
