Make your Replit 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 Replit Keep keys in Replit Secrets rather than in code files, and check none were printed to logs or committed earlier.

• 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 Replit If the Agent built its own login, check that passwords are hashed and that every API route checks who is asking.

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

In Replit Know where your data lives and how you'd get it out. Keep a backup somewhere outside the Replit project.

• 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 Replit Keep the development workspace separate from the deployment real users reach, so experiments never land on them. The Agent can change more than you asked for, so review its changes before they deploy.

• 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 Replit Watch the deployment for errors and downtime, and decide in advance what happens if the platform itself goes down.

• 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 Replit Agent usage and your deployment bill are separate from the AI calls your app makes. Put limits on those calls so a loop or a heavy user can't run up the bill.
