To anyone feeling a desire to reflexively dismiss Alpine.js, I'd strongly suggest taking an hour or two rewriting a toy project that uses Stimulus JS into Alpine and give it a fair comparison.

If you haven't ever used Stimulus, then I'd be doubly cautious about making a snap judgement. If you're the type who writes every single site as a SPA, then this library isn't for you.

Alpine is gaining traction quickly in the Laravel world and isn't going to be disappearing in the near future. On the contrary it's likely to expand and gain adoption in other MVC framework ecosystems. I, for one, am seriously considering for my next Phoenix project.
