Is my Lovable app secure?
It can be, but apps from Lovable and other AI builders often ship with the same few holes: database tables anyone can read, secret keys in the browser, backend functions that don't check who's calling, and limits enforced only in the frontend. Check for those before you share the link.
Why
AI builders produce working apps quickly, and the security rules are the part that's easiest to get subtly wrong: the app works in testing, so nobody notices that the database also answers strangers.
The most common problems: Supabase tables with RLS off or a policy that lets anyone read; a service_role or other secret key in a VITE_ variable; edge functions that send email, take payments or return files without checking the caller; users able to edit their own plan or credits; and free-plan limits that only the UI enforces.
None of this means you did something wrong. It means you should check once, fix what's found, and check again after big changes.
How to check
- Scan your published URL with Shippable: you add a one-line tag to prove it's yours, then it checks what anyone can see from outside.
- For the issues only visible in the code (functions, policies, limits), run npx shippable-dev scan localhost:5173 in your project, or add Shippable to your AI agent.
- Paste the fix prompts back into Lovable, then re-scan to confirm each one is gone.

Your first app is free, and it is read-only. You prove the app is yours with a one-line tag first.
