Vibe-Coded App Rescue: Fix and Harden Your AI-Built App

What is a vibe-coded app rescue?

A vibe-coded app rescue is a scoped job in which a developer audits an app generated by prompting, closes what can leak data or lose money, adds tests, and repairs or rebuilds what fails, then hands the app back in accounts you own. Screens and data stay wherever they are sound. What changes is that someone has read the code and answers for it. The same job is also sold as vibe coding cleanup, or as hiring a Lovable, Bolt or Replit app developer.

I am a full-stack developer with 13+ years and 900+ projects, and CTO at ElySpace, a hosting company, since 2016. I build with Claude Code and review every change myself, so I know where generated code tends to go wrong. To try the fix yourself first, read my guide on how to fix a vibe-coded app. This page is the service.

What problems does a vibe-coded app rescue fix?

It fixes apps that break, leak, slow down or cannot leave the builder. Each symptom has a likely cause that I check early.

Fixes follow risk, not the order you noticed things: exposed data and money first, then data integrity, then your bug list, then new features.

What does the rescue audit check?

It checks where generated code most often looks finished but is not, and every finding comes with evidence rather than an opinion.

Many of these apps run on Supabase; Lovable's built-in backend "utilizes Supabase's open-source foundation." Once row-level security is on, the publishable key reaches no data "until you create policies", so I test each policy on staging first and add the pgTAP policy tests Supabase documents, so a later prompt cannot quietly reopen a table. The reasoning behind each row is in my vibe coding security checklist.

Which AI app builders and coding tools do you work with?

Lovable, Bolt, Replit, v0, Cursor, Claude Code and similar tools, as long as the code can reach a Git repository you own. The way out differs on each, and so does what stays behind.

If the code cannot be exported to an account you own, I recommend a rebuild, because every fix would stay locked in the platform. My guide to vibe coding tools compares what each one lets you take with you.

Is the builder's own security scan enough?

No. A builder's scanner is a useful first pass, and I run it, but its makers say it is not a full review. Lovable's security documentation says its tools "help identify common security issues, but they cannot guarantee complete security," and suggests "an additional professional security review" for apps with sensitive data. Replit's Security Center calls its build-time check "an early, lightweight check in the Agent workflow rather than a full codebase review."

Scanners find patterns; they cannot know your business rules, such as which staff role may issue a refund or which customer may see which record. Testing those takes a person signed in as the wrong user on purpose.

Will you repair my app or rebuild it?

The audit decides, and the report says which and why. Repair fits when the problems sit in a few known places. A refactor fits when each change breaks something else: tests first, then restructuring in steps. A rebuild fits only when the foundation is wrong, such as records with no owner, and it is often partial, replacing one module while the data and working screens stay. A full rebuild I quote as SaaS development on tested base code.

How do you handle my accounts, keys and customer data?

Through invitations and a staging copy, never passwords pasted into a chat. You add me to GitHub, hosting and the database under my own login, so you see what I do and can remove me afterwards. If the audit finds a key that is already exposed, I tell you at once rather than waiting for the report, and we follow Supabase's order: "Fix the root cause of the leak before you rotate anything."

The AI agents I run never receive production credentials or real customer records. Production changes happen only after you approve the fix list, with a backup first and a way to roll back. If the server underneath needs work too, that is server security hardening.

Should you buy a bug-fix package or an audit first?

Buy a bug-fix package when you know every problem and the app holds no real data. Start with an audit when users, payments or personal data are involved, because the costly problems are the ones nobody has reported. Whoever you hire, ask:

• Will you test access as a second user and signed out?
• Do I get the findings in writing, with evidence?
• Where will the fixed code live, and under whose account?
• Which fixes come with automated tests?
• What happens to keys that were already exposed?

What will a rescue not do?

A rescue makes an app safer and easier to change; it does not make it unhackable, and I make no such promise. It is not a penetration test, a compliance assessment or a certificate; if a client or regulator asks for one, you need a dedicated firm, and the rescue helps you prepare. I fix your app and its accounts, not the builder platform. I add no features until exposed data and payment problems are closed, and I do not quote fixes for code I have not read. To start a new product with AI agents and review from day one instead, hire a Claude Code developer.
