Free Fixes for Errors GenMB Finds (and Why We Stopped Fixing Apps Behind Your Back)

There is a complaint we hear about AI app builders again and again: the tool breaks your app, then charges you credits to fix what it broke. Ask for a fix, it fails, ask again, pay again. That loop is the fastest way to lose trust in a product, and we did not want GenMB anywhere near it.

So as of 26 September 2026, this is how GenMB handles errors.

We test your app after every change

After every change, GenMB loads your app in a real browser and checks it. It only flags the app when it is truly broken: the page does not load, it is blank, a file will not compile, or it shows the crash screen. Before it tells you anything, a second check confirms the problem.

That second check matters. A warning in the console is not a broken app, and a hiccup on one load is not either. If we cried wolf over minor noise, you would learn to ignore us, and then miss the time it really mattered.

Fixes for breakage we find are free

When GenMB finds breakage like that, fixing it costs you nothing. You click Fix now, and GenMB gets up to two tries per error, free. If a freshly generated app shows an error, the first automatic fix attempt is free too.

Our reasoning is simple. If our check found the problem, it is our problem. You should not pay credits because we shipped something that does not load.

New features and changes you ask for in chat still use credits as normal. The free part is fixing breakage that GenMB detects.

We never change your app behind your back

We used to run an automatic healer in the background. It would spot an error and quietly rewrite code on its own. When we audited it, it did not help often enough to justify changing code you had not asked anyone to touch. So we removed it.

We removed it. There is no silent background auto-fix in GenMB any more. GenMB never changes your app without asking. When something is broken, you see a banner and a Fix now button, and nothing happens until you click it.

We only say "Fixed" when it is

A fix you cannot see is a fix you cannot trust. So when you click Fix now:

• The chat shows exactly what GenMB changed.
• A new version is saved, so you can undo it in one click.
• GenMB re-tests your app and only says fixed when the check is clean.

If two tries do not solve it, GenMB does not keep going and does not keep guessing. It offers to restore your last working version, so you are back to an app that loads.

What this means for you

You can build without worrying that a bug will quietly eat your credits. If GenMB finds your app broken, fixing it is on us. If you want something new, you ask for it and you decide.

We think an AI app builder that fixes its own errors for free, and tells you the truth about whether they are fixed, is the least you should expect. Now it is what you get.
