Alpine.js versus Htmx
Compare	Alpine.js	Htmx
Verdict	Worth it	Depends
Best for	Server-rendered apps needing light interactivity	Server-rendered CRUD and admin apps
Who it's not for	Complex SPAs with heavy state . use React or Vue	Apps needing rich client state: editors, dashboards, offline-first
Privacy	Two CVEs appear in public databases; a CSP build exists for strict content-security policies.¹¹	Maintained OSS with a published security policy; no CVEs found in reviewed sources, but CSP compatibility is a known friction point.
Support quality	Active GitHub community, no official support	No vendor; community-only evidence found.
Public sentiment	Users love Alpine for lightweight HTML interactivity but flag performance limits, CSP friction, and Vue comparisons for bigger sites.^³	Developer opinion is polarized: fans praise the simplicity, code reduction, and speed, while skeptics report a complexity ceiling and awkward security integration.
Biggest gotcha	Default build uses eval; strict-CSP sites must adopt the separate CSP build^⁹	Inline hx- attributes clash with strict CSP; you will need nonce/hash configuration work
