Despite HTMX being backend-agnostic, I heard it pairs extremely well with Django, so that's probably why! Maybe the two are particularly well fitting pieces of the web dev puzzle.

I love Django and its my primary weapon of choice. But due to its structure and philosophy it doesn't move as fast as e.g. Rails (e.g. impressive how quickly they picked up SQLite for their Solid* stuff). I guess HTMX was a very welcomed solution from the "outside" to allow more interactive frontends.
