Founder beta • v0.5 live • App rescue for AI-coded chaos

AI broke your app?

Upload or paste the last working version and the broken version. BuildLock checks what changed, what disappeared, and what likely broke so you can fix it without wrecking everything else.

88- missing button id #searchBtn

144! risky: replaced fetch path with stub

Risk score: 72 / 100
Next step: restore old loader, patch only target function.

Stop guessing what the AI broke.

Most AI coding failures come from hidden regressions: deleted functions, changed IDs, missing event listeners, stubbed data, or patches that touch way more than they should. This MVP finds the obvious damage first.

1. Save the good build

Keep the last version that actually worked. That becomes your frozen baseline.

2. Compare the broken build

Paste or upload the new version after the AI patch caused issues.

3. Get a repair direction

See risky changes, missing pieces, and a safer prompt to repair without starting over.

Real case study: ApexIQ.

This product exists because AI patches kept fixing one thing and breaking another. The point is simple: protect the last working build before accepting another generated patch.

Launch angle: “I built this after AI kept breaking my own app. Now it compares the working version against the broken version and shows the damage.”

What BuildLock is watching for

1

Frozen features removed.
Functions, IDs, event listeners, and renderers disappear during “small” fixes.

2

Live data replaced with stubs.
Promise.resolve, mock data, placeholders, and fake loaders make a build look fixed while killing real behavior.

3

Loops cause mobile freezes.
New intervals and observers can trigger duplicate fetches, scroll bugs, and black-screen crashes.
