Lovable Security Checklist

Lovable app security checklist — check before you launch

Lovable makes it incredibly fast to build a real app on Supabase — and that speed is exactly why generated apps ship with predictable security gaps. This checklist covers the issues we see most often in Lovable-built apps, written for founders without a security background.

1. Supabase Row-Level Security (the #1 Lovable risk)

Lovable apps almost always use Supabase. If RLS is off, anyone with your public key can often read every user's data.

• RLS is enabled on every table Lovable created
• Every table has a policy scoping rows to auth.uid()
• No table relies on the frontend to filter which rows a user sees

2. Exposed keys & secrets

• No Stripe, OpenAI, or other secret keys pasted into components or prompts
• The Supabase service_role key never appears in frontend code
• Secrets live in Lovable's environment settings, not hardcoded strings

3. Authentication

• Protected pages check the session on the server/database side, not just by hiding buttons
• Admin-only actions verify the user's role — not just an isAdmin flag in the browser

4. Edge functions & APIs

• Edge functions validate their inputs before using them in queries
• Functions that mutate data require an authenticated user

5. Before you share the link

• No console errors on the published app
• Tested logged out — private data isn't visible without a session
• A security scan shows no critical issues

Questions founders ask

Is Lovable safe for production?

Yes — after you verify the generated code. Lovable optimizes for a working app, not a hardened one. The gaps above are fixable in an afternoon once you know they're there.

How do I scan my Lovable app?

Copy the generated code (or connect your GitHub sync) into VibeSafe — it flags missing RLS patterns, exposed keys, and auth gaps, and explains every fix in plain English.
