I would probably not build an actual app with HTMX but I found it to be excellent for just making a completely static page feel more dynamic. I'm using it on my two blogs and it makes the whole experience feel much snappier and allows me to carry through an animation from page to page.

The amount of custom stuff I needed to add was minimal (just mostly ensuring that if network is gone, it falls back to native navigation to error out).

Examples: https://lucumr.pocoo.org/ and https://dark.ronacher.eu/

I also found Claude to be excellent at understanding HTMX so that definitely helps.
