Is your vibe-coded app safe to launch? A production-readiness checklist

AI builders like Lovable, Bolt, Cursor and Replit get you most of the way to a working app astonishingly fast. The problem is the last 20%, the part that decides whether you’ve shipped a product or a liability.

We’ve reviewed enough AI-built apps to know what breaks. Here’s the checklist we run before we’d let one go live.

Security

• Secrets and API keys, none hard-coded in client-side code or build logs. Move them server-side or behind a proxy.
• Row-level security, if you’re on Supabase or Firebase, RLS is configured and tested, not left open.
• Authentication, sessions, OAuth or JWT implemented properly, not faked in the frontend.
• Input validation, every field and endpoint checked against the OWASP Top 10 (SQL injection, XSS, RCE).
• Access control, try to reach every page and endpoint while logged out. If you can, so can an attacker.

Data

• Know exactly where user data lives and who can reach it.
• Automated backups exist and have been restored at least once.
• Sensitive data isn’t leaking through API responses or logs.

Reliability

• Rate limiting before someone burns your API bill.
• Error tracking and monitoring so you find out before your users do.
• A real dev/staging/production split, not editing live.

The honest part

Most of this is invisible until it fails, which is exactly why AI builders skip it and why founders don’t notice until it’s a problem. AI can write the code. Making it safe to ship is still engineering.

If that list made you nervous, that’s what our Vibe-Code Rescue service is for, we fix it and get you live.

Frequently Asked Questions

What is the last 20% of a vibe coded app that needs checking before launch?

The final stage covers security, data handling and reliability rather than feature building. AI tools produce functioning screens quickly, but server-side protection, access rules and monitoring are often missed. These elements stay hidden until something breaks, so a structured review is needed before real users and data are exposed.

How should API keys and secrets be managed in an AI generated app?

Keys must never sit in client code or build logs where they can be extracted. The safe approach is to keep them on a server or behind a proxy that forwards requests. This prevents strangers from abusing connected services and racking up costs or stealing data.

Why is row-level security important for Supabase or Firebase apps built with AI?

These platforms expose data through rules rather than a traditional server. If those rules are left open, any user can read or change records. Testing the configuration confirms that each account only touches its own data. Without this step, a simple query could leak every user’s information.

What reliability measures should be in place before a vibe coded app goes live?

A separate staging environment lets you test changes without affecting users. Rate limiting stops a runaway script from inflating your API bill, and error tracking alerts you to faults before customers complain. Together these steps keep the service running once real traffic arrives.

When should you consider a vibe code rescue service for your AI built app?

If a review of security, data backups and access controls raises concerns you cannot fix alone, outside help makes sense. Projects at entry £10,000-£50,000 often need a focused cleanup, while larger mid £50,000-£150,000 builds may require deeper rework before they are safe to launch.
