90% of vibe-coded apps have at least one critical vulnerability

15 security rules every vibe coder needs before shipping:

1. Never build authentication with AI alone use proven auth providers
2. Keep every secret in environment variables, never inside your code
3. Set session expiration so stolen tokens cannot live forever
4. Verify every package AI suggests before installing it
5. Sanitize all user inputs before they touch your database
6. Add rate limits to your APIs to stop bots and abuse
7. Always enforce permissions on the server, never trust the frontend
8. Make storage private by default so users only access their own files
9. Restrict CORS to your real domains instead of allowing everything
10. Remove debug logs before deploying to production
11. Validate redirect URLs so attackers cannot hijack them
12. Set spending limits on AI APIs to avoid runaway costs
13. Verify webhook signatures before processing external events
14. Log critical actions like payments, role changes, and deletions
15. Keep test and production environments completely separate

Save this. Your future self will thank you
