That's pretty much true of HTMX too (which is what GP mentions using). I mention Hotwire Native (different from plain Hotwire) because it makes it easy to wrap a web app as a mobile app. Then you can replace performance critical parts with native views, but keep everything else working through the web app portion. This is easier to maintain, albeit with the downside that everything requires network round trips. Depending on you use case, that may be an acceptable tradeoff.
