Django is more or less Python's equivalent of Rails. Its admin panel is nice, especially for a solo developer trying to manage something they built in a weekend.
Filament, and it’s fucking awesome. I think it’s way better than Django’s admin panel, and I’ve used it to build out both my Laravel admin panel and basically all of the UI for users.
With admin, you basically just write models, and the entire rest of your app is free. Not quite, but, not far off.
