Free Lovable security scanner
Lovable gets you from idea to live app in an afternoon, on top of Supabase. The catch: Supabase is only as safe as its Row Level Security policies — and in 2025, over 170 Lovable apps were found leaking user data because RLS was off (CVE-2025-48757).
What we check on Lovable apps
Typical stack: React + Vite + Supabase
Your Supabase anon key ships to every visitor by design — that's fine only if Row Level Security is on. With RLS off, anyone can copy the key from the network tab and download every row. VibeShield checks each exposed table's row count (never the data itself).
An OpenAI, Stripe or Resend key used directly in a React component is readable by anyone. It belongs in a Supabase Edge Function. VibeShield flags secret keys in your shipped JavaScript — and tells a service_role key apart from the harmless anon key.
If Supabase auth auto-confirms new accounts, anyone can register with an address they don't own — and any policy that trusts “signed-in” users trusts them too.
No Content-Security-Policy, HSTS or clickjacking protection means one injected script or a framing attack goes unchecked. VibeShield tells you which headers are missing and what to set.
