Overview
Open-source Postgres backend with auth, storage, and auto-generated APIs. The default database behind Lovable and much of the vibe-coding ecosystem. Its row-level security model is powerful but off by default on new tables, which is the single most common root cause behind publicly readable data in shipped vibe-coded apps.

Security scan data
Not yet scanned. Supabase has not been through our aggregate scan pipeline yet. Grades on this site come from passive, read-only scans of real shipped apps, never from vendor claims, and we do not publish a grade until the sample is large enough to be defensible.
How grades are produced, and what counts as a defensible sample, is documented on the methodology page.
