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.
CheckVibe scans the deployed site directly (the layer where Lovable apps actually fail) and scores SEO + AEO in the same pass.
What Lovable leaves for you to secure
Live anon-key reads against your tables
Supabase, OpenAI, Stripe & more in your JS

Weak transport, insecure session cookies
Whether ChatGPT and Google can read your SPA

Frequently asked questions
- How do I scan a Lovable app for security issues?
- Paste your published Lovable URL into CheckVibe, no GitHub repo, no export, no account needed. 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 with no signup, and you see your issue count and a sample finding immediately. A free account unlocks the full breakdown; 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.
- Does CheckVibe help my Lovable app rank too?
- Yes, and it matters for Lovable specifically. Lovable apps are client-rendered SPAs that often serve AI crawlers an empty shell, so they’re invisible to Google and ChatGPT no matter how good the content is. CheckVibe scores SEO and AEO (AI-search visibility) in the same scan and tells you how to fix it.
