I’ve been using it for projects where a non-JS backend mostly handles templates, but I still want modern JS framework-like interactivity. A nice thing compared to Vue and React is that Alpine takes its template from your HTML, not your JS, so all your JS needs to have is the controller data logic, and the actual template stuff can be with your non-JS template code.

Clearly you have never used Vue, because it works in the exact same way.

Alpine looks like Vue without computed properties.

I have used Vue. In Vue, the templates are compiled and included if you use SFC, which is the preferred method. If you don’t use SFC, you have to ship the Vue compiler to your clients and that is not small. It’s a tradeoff.

Alpine doesn’t have a VDOM, so there’s no compiler and no equivalent of SFCs.

Sure! Basically we had a thorny problem that needed to be solved on the frontend- users would be picking a plan, adding a payment, and possibly applying a promo code. JS is a prerequisite for Stripe payment collection and in general this solution would have been a non-starter in a backend template. But this was the only such page in the application, so it really felt like overkill to integrate an SPA like Vue or React. Vue's drop-in CDN is close, but there's still some setup boilerplate that was nice to do without.
