To rescue an AI-built MVP, audit it before you change anything: check security, data handling, tests and structure, then decide whether to stabilise it, refactor the worst parts or rebuild the core. Most can be saved if the idea is proven, but you should fix the risky parts first and keep what users already value.

## Why these projects need rescue

An app built quickly by prompting often works well for a demo and badly under real use: security gaps, fragile data handling, no tests, and code that nobody on the team understands. When something breaks, nobody knows where to look.

## Step 1: Audit

| Area | What to look for |
|---|---|
| **Security** | Authentication, authorisation, secrets in code, input validation |
| **Data** | Where it is stored, backups, personal data, schema quality |
| **Tests** | Do any exist, and do they test real behaviour? |
| **Structure** | Folders, duplication, tangled files |
| **Dependencies** | Outdated, unused or unsafe packages |
| **Deployment** | How it is released, monitoring, error reporting |
| **Ownership** | Who owns the code, accounts and domain? |

## Step 2: Stabilise

- **Rotate any exposed secrets** and move them to environment variables.
- **Fix serious security gaps,** especially access control.
- **Back up the data** before you touch anything.
- **Add basic monitoring** so you see failures.
- **Write tests** around the behaviour that must not break.

## Step 3: Choose a path

| Situation | Path |
|---|---|
| Mostly sound, a few weak spots | Fix and refactor in place |
| Good idea, messy code | Refactor module by module, behind tests |
| Wrong foundations | Rebuild the core, keeping the data and learnings |

## Step 4: Keep learning

Keep what users liked. The screens, flows and feedback are valuable, even if the code is not. Document the rules the app follows and use them as the specification for any rebuild.

## Step 5: Prevent a repeat

Adopt review, testing and small changes from now on. See [AI coding do's and don'ts](/blog/ai-coding-dos-and-donts), [reviewing AI-written code](/blog/reviewing-ai-written-code-checklist) and [technical debt from AI code](/blog/technical-debt-from-ai-code).

## FAQ

### Can an AI-built app be saved?
Often yes. Audit first, fix the risky parts, add tests and decide whether to refactor or rebuild the core.

### Should I rebuild from scratch?
Only if the foundations are wrong. Many apps can be stabilised and improved step by step.

### What is the first thing to fix?
Security gaps and exposed secrets, then data backups.

### How do I avoid this next time?
Review all code, test, keep changes small and have a developer own the architecture.
