Can Alpine.js be self-hosted?

We have only confirmed a cloud / SaaS deployment for Alpine.js, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.

The vioscaleAI score: one lens on the evidence

Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Alpine.js, not the verdict.
