Vibecheck: Is Your AI-Built App Leaking?

Why it surfaced

Vibecheck turns a recurring AI-app failure mode—publicly readable tables and missing security headers—into a quick report card. The scan runs in the visitor’s browser, claims to store nothing, and comes with a pointed instruction: test only apps you own or are authorized to test.

A free, open-source browser-based security scanner that checks what strangers can read from an app and its Supabase or Firebase backend.
