Here are two Python ones I've tried:
https://www.django-unicorn.com/ https://github.com/edelvalle/reactor
This tool does play very nicely with Django's templating engine; you can just have HTMX re-render a particular template block on the server, and send down that updated block. The migration path is quite clean; you just wrap your "HTMX-updated" template block in a `hx-post` div.
Having not gone too deep on HTMX, I'm interested in folks' thoughts on where it's lacking vs. LiveView and Hotwire. One area I can see is performance; Elixir is going to be faster than Django, and so if you're trying to handle high session counts over websockets. But the impression I get is that HTMX is a bit more light-weight, so I'm wondering if there's usecases that can't be met with it vs. LiveView.
Other Django libraries that haven't quite seen as much uptake:
We have https://github.com/edelvalle/reactor, and a port of Hotwire: https://github.com/hotwire-django but both of these don't seem to have much adoption (yet!).

I am using Hotwire for a project, and I'm learning Elixir and Phoenix on the side. Finding edelvalle/reactor was immediately helpful to me though, because I cut my teeth on Python/Django, so reading a Python reference implementation helps me learn nuts and bolts of libraries, faster. (so, I figure that this might help someone else grok how these approaches work.)
For those interested in LiveView-esque functionality in other frameworks , there are some similar projects cropping up:
- Django Reactor https://github.com/edelvalle/reactor
- Laravel Livewire: https://laravel-livewire.com/
- Rails Stimulus Reflex: https://docs.stimulusreflex.com/
