How do I fix a Lovable app that keeps breaking?

Updated 2026-08-19

First, stop asking the AI to fix it. Every prompt can rewrite working code, and with no tests to catch it, each fix quietly breaks something else. That loop is why the app keeps breaking and why your credits keep disappearing. Instead: revert to the last version that worked, connect the project to GitHub so the code exists outside Lovable, then make one small, specific change at a time. If it is a permissions or login problem, the cause is usually Supabase row level security settings, not the app code. If the app matters to your business and the loop will not end, get the code out and have a person diagnose it. That is a bounded, one-time cost instead of an endless subscription to breakage.

Break the loop before you fix the app

Here is the cycle that brought you to this page. Something broke. You told Lovable to fix it. It did, and a day later something else was broken. Repeat until you are out of patience or out of credits.

The cycle is not bad luck. When you prompt for a fix, the AI rewrites code, and it will happily rewrite code that was working. A professionally built app has tests that catch that immediately. A generated app has none, so every fix is also a small gamble on the rest of the app, taken blind. Asking more is not converging on a fixed app. It is re-rolling the dice, and on a platform that charges per message, you are paying for each roll.

So the first fix is behavioral: stop prompting for fixes.

Three things to do right now

Revert, don’t repair. Lovable keeps a history of your project’s versions. Rolling back to the last version that actually worked is one click and beats untangling three layers of failed fixes. You lose the recent “improvements”, which is fine, because they are what broke it.

Get the code into GitHub. Lovable can sync your project to a GitHub repository you own. Do it today even if you never plan to leave. It costs nothing, it is a real backup outside the platform, and it is the thing that lets any developer, hired or borrowed, actually look at your app. An app that exists only inside the tool that keeps breaking it is a bad place to store a business.

Export your data. Your app’s data lives in Supabase, under your own account. Make sure you can log into it and take a backup. Broken features are recoverable. Lost customer data is not.

If it still breaks after that

Change how you prompt. One small, specific change per message, “the submit button on the contact form shows an error, fix only that, change nothing else”, then check the app before the next one. Vague prompts like “make it stop breaking” produce big rewrites, and big rewrites are the disease.

And if the symptom is logins failing, users seeing the wrong data, or permission errors, the problem is probably not the app code at all. It is usually the row level security rules in Supabase, the settings that say who may read and write which data. Generated apps routinely ship with these wrong or half-finished. This one is worth a professional look even if everything else works, because the failure mode is not a crash, it is your customers’ data being readable by the wrong people.

When to hand it over

If the app is part of how you make money and the loop will not end, the economics flip. Prompting is an open-ended cost with no guarantee. A human diagnosis is a bounded one: someone reads the code, tells you what is actually wrong, and gives you a straight fix-or-rebuild call. We wrote up what that costs, and the short version is that the assessment is cheap compared to another month of the loop.

For the bigger picture of why AI-built apps do this, prototypes quietly becoming production systems, see vibe coding: why the app works until it matters. And if you want a person to look at yours, that is our app rescue lane: send us what you built and we will tell you where it stands.

Questions people ask

Why does every fix break something else?

Because the AI does not patch your app the way a mechanic patches a car. It rewrites code, sometimes code that was working, and the app has no tests, so nothing catches the new breakage until you or a customer hits it. You see the thing you asked about get fixed and you do not see what got rewritten behind it. That is the whole loop.

Do I actually own my Lovable app?

The code, yes. Lovable can sync your project to a GitHub repository you own, and doing that should be your first move, before any more fixing. Your data lives in Supabase, which is a separate account you control and can export from. Owning both is what makes every later option possible, including leaving.

Is Supabase the problem?

Usually not Supabase itself. Lovable apps store their data in Supabase, and the most common real breakages, login problems, permission errors, users seeing data they should not, come down to row level security rules that were generated wrong or never finished. That is configuration, and it is fixable, but it is exactly the kind of thing the prompt-until-it-works loop is bad at.

Will more prompting eventually fix it?

Sometimes, on small apps, with very specific prompts and one change at a time. But if you have been going in circles for days, the honest answer is no. The app needs the things the generator skipped, tests, error handling, checked permissions, and those get added by engineering, not by asking again. More prompting from here is paying per attempt for coin flips.
