Comparison
Use the AI builder. Until it starts holding money.
We repair Lovable, Bolt, v0, Cursor, Replit and Base44 builds for a living, so this is not an argument against them. It is a description of the four points where generated apps reliably stop being adequate, observed from the ones that arrive broken.
Keep using the builder
Four cases where the AI builder is the right answer
A studio that told you to never use these tools would be selling you something. These are the situations where we would use them too.
You are testing whether anyone wants it
A clickable prototype in front of ten real users is worth more than a perfect architecture nobody asked for. AI builders are better at this than we are, and you should use them.
The product is the interface
Landing pages, internal dashboards, single-user tools, form-driven apps. If nothing sensitive is stored and no money moves, the risks below mostly do not apply.
You need it this week
A pitch demo, a waitlist, an internal tool for four people. Speed beats everything else here, and rebuilding later is cheap because there is little to rebuild.
You can afford to throw it away
The healthiest way to use these tools is as a disposable answer to a question. Problems start when a disposable build quietly becomes the production system.
Where it breaks
Four points where generated apps stop being adequate
Each of these is a pattern we have been paid to repair, not a hypothetical.
Money starts moving
The single most common rescue we see. Checkout succeeds, Stripe shows the charge, and the database has no order, because the browser redirect was treated as proof of payment instead of a verified webhook. Once real customers are paying, this stops being a bug and becomes a refund queue.
A second user type appears
Teams, organisations, admins, or anything where one person should not see another's data. Row level security disabled on a hosted database is the most serious finding we make, and the app looks completely normal until somebody checks.
You need to change it without breaking it
The fix-and-break cycle: you prompt for one change, the model rewrites a file it should not have touched, and something unrelated fails. With no tests and no deployment path, every fix is a gamble and credit spend climbs while the product gets worse.
Someone becomes liable for it
The moment a real customer depends on the output, silent failures stop being acceptable. Most generated apps swallow errors and return success, so the first report of a problem comes from a user rather than from monitoring.
Check it yourself
Tests you can run in ten minutes
You do not need us to tell you whether your build has these problems.
- Log in as one user, then change a record id in the URL or request and try to read another user's data. If it returns, row level security is off.
- Make one real payment end to end, then check the database directly for the order. If the row is missing, your payment state is inferred rather than recorded.
- Break something deliberately, a bad API key or a failing write, and see whether anything alerts you. If nothing does, failures are silent by default.
- Ask the builder to change one thing, then check three unrelated features still work. If they do not, you are in the fix-and-break cycle.
Including the two rows we lose
What each option actually costs you
| AI builder | A studio | |
|---|---|---|
| Time to something clickable | Hours | Day one |
| Time to production | Days, if nothing real depends on it | 21 days, fixed price |
| Cost up front | A subscription | From $3,999 |
| Cost when it breaks at scale | A rescue engagement, or a rebuild | Included: two weeks of fixes, then a 30-day programme |
| Who is accountable | You | A named senior engineer |
| Handles money and multi-user data safely | Only if you engineer it yourself | By default |
| You own the code | Yes | Yes, from day one |
The cheapest path is usually neither extreme: prototype in the builder, validate that anyone wants it, then rebuild the parts that hold money and identity properly. That is what most of our rescue engagements turn into.
Questions, answered
Should I avoid Lovable and Bolt entirely?
No. We would use them ourselves for a prototype, an internal tool, or anything disposable, and we tell founders that on calls. The failure is not the tool, it is keeping a disposable build in production after it has started holding money and other people's data.
Can my existing AI-built app be saved, or does it need a rebuild?
Usually saved. Most of these builds have sound intent and unsafe execution: the data model is broadly right and the security, payment integrity and error handling are missing. We only recommend a rebuild when the core structure cannot support what the product actually needs, and the free audit tells you which case you are in before you spend anything.
How do I know if my app has these problems right now?
Three checks you can run yourself. Log in as one user and try to fetch another user's record by changing an id. Make a real payment and confirm a database row exists afterwards. Break something on purpose and see whether anything alerts you. If any of those goes the wrong way, the others usually do too.
What does it cost to move from an AI build to something production-ready?
The first audit is free and comes back in 48 hours with written findings and a fixed quote for the repair scope. Repairs are quoted per engagement because the work depends entirely on what is broken. A full rebuild starts at $3,999 and ships in 21 days.
