The short answer
Vibe coding — describing what you want and letting AI write the code — is the fastest way ever to get a working prototype. It's genuinely great for testing an idea. But a prototype that works for you is not the same as production software that works for thousands of strangers, handles their money and data, and doesn't fall over at 2am.
The good news: you rarely need to throw it away.
Where vibe-coded apps break
- Security. API keys in the browser, missing server-side checks, database rules that let any user read any row.
- Access control. Features that assume the user is who they say they are, with nothing enforcing it.
- Data integrity. No migrations, no validation, no backups — one bad change and the data is gone.
- Payments. Webhooks not verified, double charges, subscriptions that never cancel.
- Scale and cost. Queries that are fine with ten users and melt with ten thousand; AI calls with no limits.
- Maintainability. Code nobody understands, with no tests to say whether a fix broke something else.
The red-flag checklist
If any of these are true, get an engineer to look before you onboard real users:
- Secrets or keys appear in front-end code.
- You can't explain who can read or change each piece of data.
- There are no automated tests.
- There is no staging environment — changes go straight to live.
- You don't have tested backups.
- Payments or personal data are involved.
Keep, fix or rebuild
The fastest path is usually not a rewrite:
- Keep the product thinking, flows and UI you've validated — that's the valuable part.
- Fix security, access control, validation and payments on the existing code where it's sound.
- Rebuild only the parts that are unsafe or can't scale — often the data layer and auth.
Vibe coding and senior engineers work best together
We use AI heavily in our own delivery — it's a big part of how we ship in weeks. The difference is that senior engineers decide the architecture, review what the AI writes, and own security, data and testing. That's what turns speed into software you can trust.
How Softgen helps
We take vibe-coded and AI-built prototypes to production: an audit that tells you what to keep, fix or rebuild, then a fixed-price plan to get there. Start with a Discovery Sprint or read how to add an LLM to an existing app.
