Lovable security scanner
No GitHub repo needed, just paste your Lovable URL. CheckVibe scans the live app for public Supabase tables (probed with your anon key), exposed keys in the bundle, and missing headers in about 30 seconds, with a copy-paste fix for each one.
Free account required to see the results
CheckVibe scans the deployed site directly — the layer where Lovable apps actually fail. Security findings land in your dashboard rather than on a public page; the account is free. The SEO and AEO scanners need no account at all.
What Lovable leaves for you to secure
Live anon-key reads against your tables
Supabase, OpenAI, Stripe & more in your JS
Missing CSP/HSTS, wide-open origins
Weak transport, insecure session cookies
Connect the repo: code flaws, packages, secrets
Each finding as a Claude/Cursor fix prompt
Three steps. No repo required.
- 01
Paste your Lovable URL
No export and no repo. CheckVibe scans the published app directly; a free account holds the report.
- 02
Live checks run
It probes Supabase RLS with your anon key, scans the bundle for secrets, and tests headers and CORS.

Fix in Lovable
Each finding ships as a copy-paste prompt you can paste straight back into Lovable, Claude, or Cursor.
Frequently asked questions
- How do I scan a Lovable app for security issues?
- Paste your published Lovable URL into CheckVibe, no GitHub repo and no export needed, then a free account for the report. It scans the deployed site for the issues Lovable apps ship with most: Supabase tables without Row Level Security, the anon (or service-role) key in the bundle, missing security headers, and permissive CORS. Results come back in about 30 seconds.
- Why do Lovable apps need a security scan?
- Lovable builds a client-rendered React app on a Supabase backend and optimizes for a working demo, not a hardened one. The two layers that fail most (live RLS state and what’s actually in the served bundle) are invisible to a code review but exposed on the live URL. That’s exactly what a URL scan sees.
- Do I need to connect my repo or Supabase project?
- No. CheckVibe needs only your public URL. It reads what any visitor’s browser gets, finds your Supabase project from the bundle, and tests table access with the public anon key, no repo access, no database password, no service-role key.
- Is it free?
- Yes, scanning is free. It does need a free account, because the findings are a map of how to get into your app and that belongs in your dashboard rather than on a public page. Paid plans add copy-paste fix prompts (the exact RLS policy or header config) plus continuous monitoring as you keep iterating in Lovable.
- What’s the most common Lovable security mistake?
- Supabase tables left without RLS. The anon key in your bundle is public by design, so an unprotected table is readable by anyone who opens DevTools. CheckVibe verifies this live rather than just reminding you it exists. See our free Supabase RLS checker for that specific test.
- Can CheckVibe also scan the code Lovable wrote?
- Yes, once the project is synced to GitHub. Connect the repo and the same account scans the code, dependencies and secrets, and on the Team plans every pull request is reviewed automatically. CheckVibe is a security platform for developer teams building with AI; the free URL scan is where it starts.
