What is the best security scanner for Lovable apps?
The best security scanner for Lovable apps tests the deployed site, not just the code. CheckVibe (from $0) leads for Lovable: 100+ checks including the Lovable-signature failure modes, plus SEO/AEO scanning no competitor offers. VibeEval, Vibe App Scanner, and Scanbee are strong security-only options.
TL;DR
- Lovable's output is a client-rendered React app on a Supabase backend — the two layers a repo-reading tool can't verify (live RLS state, served bundle contents) are exactly where Lovable apps fail.
- CheckVibe: free tier (4 scans/mo), $24–59/mo paid; the only option that also scans SEO + AEO visibility.
- VibeEval ($19/mo, $199 lifetime) goes deepest on autonomous agent-based security testing.
- Vibe App Scanner ($9–19 one-time) is the cheapest single pre-launch audit.
- All picks verified against vendor sites on June 12, 2026 — sources at the bottom.
Lovable apps are almost always Supabase-backed, which concentrates the risk: the public anon key is in your bundle by design, so any table without Row Level Security is one fetch away from being public. Add the usual AI-codegen gaps — keys in client code, no security headers, permissive CORS — and a scanner that tests the deployed app (not the repo) becomes the right shape.
How we picked
- Tests the deployed app from the outside (what attackers and crawlers actually see), with Lovable listed as a supported platform or stack-relevant coverage.
- Catches the platform's signature failure modes, not just generic OWASP items.
- Honest pricing with a usable free option where available.
- Output a vibe coder can act on — fix guidance, ideally AI-editor-ready.

Do I really need a security scanner for a Lovable app?
If the app has users, data, or payments — yes. AI-generated apps ship with a consistent set of gaps (exposed keys, missing access control, no headers), and every tool on this list catches issues a manual click-through never will. Start with a free scan; the result settles the question.
Are free security scans enough?
A free scan is enough to find out where you stand today. Paid tiers buy continuity (scheduled scans, monitoring, alerts) and depth (more pages crawled, more checks). For a side project, free-tier scans before each launch may genuinely suffice.
What is the #1 security issue in Lovable apps?
Supabase tables without Row Level Security. The anon key in your bundle is public by design; without RLS policies, anyone holding it can read entire tables. Any scanner you pick for Lovable should verify RLS live, not just remind you it exists.
Can these scanners see my Lovable source code?
CheckVibe, VibeEval, and Vibe App Scanner test the deployed URL only — no repo access. Scanbee can additionally scan a GitHub repo if you connect one. For Lovable apps, the deployed app is usually the more revealing target.
