Lovable app not working anymore? The honest emergency guide

Lovable, Bolt and co. are brilliant at building something visible in hours: a login, a dashboard, a database. What they don't deliver is the invisible part that makes an app hold up: a considered architecture, clean access control and tests. Vibe coding means accepting the AI's suggestions and no longer reading the code in detail. That works surprisingly well, for the first few days. More in the glossary entry on vibe coding.

Then it tips over. Every new feature changes spots that used to work, because the AI has no stable structure to hold on to. The code grows faster than anyone understands it. Since AI assistants arrived, GitClear measures more copied code (from 8.3% to 12.3% of changed lines) and less and less cleanup (moved lines down from 25% to under 10%). Past a certain point, every change tears open two others.

That is not your failure. It's the built-in price of speed without control. The good news: the state is measurable and in most cases rescuable. Why AI code is rarely production-ready on its own we've backed with studies and our own audit: Is AI code production-ready?

1. Every new feature breaks two old ones. The code runs, but a change in one place tears open things that used to work. That's the classic sign of missing architecture: there are no clear boundaries between the parts of the app.

2. The AI agent goes in circles. You explain the same problem for the third time, get a new variant each time, and in the end don't know which is right. The AI guesses instead of understanding the cause.

3. You no longer dare to go live. Not out of hesitation, but because nobody knows what will break on the next update. Missing tests make every release a gamble.

4. Login, payment or data misbehave. Exactly the spots that need access control are weakest in AI code. In our audit, not a single one of the authorization controls checked was met.

5. Something feels insecure. Often rightly so: keys visible in the browser, the database without protection, the .env file public. These are the most expensive mistakes, and they're checkable from the outside.

You don't have to be a developer to spot the most dangerous problems. Open your app in the browser, right-click “Inspect” and look at the “Network” and “Console” tabs. If red errors or long keys appear there, that's a warning sign.

Even simpler: enter your public URL into the decivo Scan. It checks externally visible signals in security (e.g. database keys readable in the browser, open .env files), architecture, privacy and code hygiene, and returns a clear Go, Iterate or Stop with an explanation.

It costs nothing, takes minutes, and you give no access to code or database. For a deeper check (database access control, interfaces, outdated building blocks) you optionally connect your GitHub project with read-only access, also free. What a Lovable project needs for launch is on the page Is your Lovable app production-ready?

Not every broken app has to be rebuilt, and not every one can be rescued economically. For context: of the Lovable apps in the AI App Radar, 25% (47 of 187) got a Go and 75% (140 of 187) an Iterate, meaning “needs work”. Not a single Stop. Most Lovable apps are repairable.

Rough rule of thumb: if the foundation is fine (clear data models, a reasonably clean structure) and only a few spots are on fire, a rescue is usually the cheaper path. If access control, data model and architecture are fundamentally open, a targeted rebuild on top of what already works can end up cheaper than endless patching. More on this: from prototype to product and Lovable alternatives.

Based on the findings, the scan recommends a path with the price up front: the immediate mitigation (€540 net, fixed price, closes every open high-severity gap), the repair plan (€349 net, every location in order for doing it yourselves), repair and stabilisation (from €1,090, a fixed price from your scan, binding after the repository scan) or a rebuild from €12,500.
