I would refer it as a library. Like any library, it has a bunch of functions available to use. The difference, however, is that you don't use them directly. You are just writing html with htmx tags, etc.. and letting htmx, the library, do the rest. This is it for the most part - but I understand some complications could break that rule. I doubt it would be that often if at all.
