Is my Lovable app safe to launch? 5 things to check first

Lovable apps are usually Supabase-backed React SPAs. Before you share yours, check these five things — three you can verify for free from the URL.

Lovable builds a real React app with a Supabase backend, and it does a lot right by default. But a few things are on you before you put it in front of real users.

1. Is Row Level Security on?

Lovable ships your Supabase anon key in the frontend (correct). Your data is safe only if RLS is enabled on every table. This is the number-one thing to verify.

2. Any secret keys in the page?

If you wired up Stripe, OpenAI, or another service yourself, make sure the secret key isn’t in the client. Only publishable/anon keys belong in the browser.

3. Are production source maps off?

Source maps let anyone download your original source. Fine for debugging, not for launch.

4. Basic security headers

Content-Security-Policy and friends, set at your host.

5. Privacy policy + terms if you collect data

If you have sign-up or email fields, most jurisdictions expect a privacy policy.

Items 2, 3, and 4 are checkable right now from your public *.lovable.app URL; the RLS check needs you to verify ownership (so we can test it safely). → Scan your Lovable app

FAQ

Does Lovable put my Supabase service_role key in the browser?
By default Lovable uses the public anon key in the frontend, which is correct. The thing to verify is that Row Level Security is enabled so that public key cannot read everything.

What is the most important thing to check in a Lovable app?
Whether Row Level Security is enabled on your Supabase tables. The public anon key is fine; open database rules are the real risk.
