Make your Lovable app production-ready

• Every API key and secret lives on the server, never in frontend code
• Any key that was pasted into a prompt, a chat or a public repo has been rotated

In Lovable Lovable apps usually talk to Supabase straight from the browser. The public anon key is meant to be there; a service role key or a third-party API key is not, and belongs in an Edge Function.

• Permissions are enforced on the data, not just by hiding buttons
• Signed in as two different users, neither can see the other's records

In Lovable Supabase Row Level Security policies are what actually protect the data. Check that each one tests the signed-in user, not just that a user is signed in.

• Every table that holds user data has access rules
• Backups run, and one has been restored to prove it works

In Lovable A Supabase table without Row Level Security can be read through the API by anyone holding the anon key. Turn it on for every table.

• A separate staging environment, so changes don't go straight to real users
• The code lives in a Git repository you own, so every change can be reviewed and rolled back

In Lovable Sync the project to GitHub so the code sits in a repository you own, and try risky changes on a copy before publishing.

• Errors and downtime raise an alert, so you hear about problems before users do
• Failed payments, logins and AI calls are logged where a person will see them

In Lovable The preview shows that it works for you. Error tracking shows when it fails for someone else.

• Usage limits stop a runaway loop or a heavy user from running up the bill
• The right model for each task, with caching where answers repeat

In Lovable Lovable credits pay for building. Your Supabase and AI provider bills grow with your users, so put limits on every AI call inside an Edge Function, where nobody can bypass them.
