unpoly is a more complete framework with concepts like layers and best in class progressive enhancement

htmx is lower level and focuses on generalizing the idea of hypermedia controls

HTMX is lower level. I think it would make a good web standard for libraries like Unpoly to build upon. Unpoly works best as progressive enhancement for frameworks like Rails or Django where most of the view logic is executed on the server. I love it, it's excellent. Just like Django (or rails), it's a practical tool refined after actual needs and experience, not a solution looking for a problem. And like Django it stood the test of time and is very well maintained.

LLMs know nothing about Unpoly, and quite a bit about htmx. This requires you to actually learn Unpoly, because, well, even pointing your LLM-of-choice at the Unpoly docs (which are quite okay!) makes it regress-to-the-ugly-Javascript-workarounds-mean pretty much on try #1.

I'm not yet sure whether this is a good thing or not -- I'll let you know once my latest iteration of my web framework is finally working as I envisioned, he-said sort-of-jokingly, which should be Soon Now.

But yeah, either alternative still beats React by a country mile, since everything related to that descends into madness right away.
