Your AI built app was going great. Until it wasn't.
Now the tool is stuck in a loop, the same bug keeps coming back, and every fix breaks two other things. I rescue broken apps from Lovable, Bolt, v0, Replit, Cursor, and Base44. Diagnosed for free, fixed and tested within 24 hours, explained in plain English.

What I fix
- Apps stuck in an AI error loop, where every prompt makes it worse
- Blank white screen after deploy or on a fresh clone
- Broken login, signup, and auth flows
- Supabase errors: data that saves but never shows up, permission denials, schema drift
- Buttons and features that do nothing
- Builds and installs that fail with errors the tool cannot explain
- Half finished features the AI gave up on
Why the tool that built your app cannot fix it
Lovable, Bolt, and v0 generate code but never run it. They cannot open your app, click the button, or read the stack trace. When something breaks outside their happy path, they guess. After a week of guessing, your project chat is poisoned with wrong assumptions and every new fix is built on top of them.
I do the opposite. I clone your app into a clean environment, run it, reproduce the exact failure, fix the real cause, and run it again to prove the fix. You get working code and a short note explaining what was wrong, in words you do not need to be a developer to understand.
A real rescue, measured
A campus delivery app built with Lovable worked on its owner's machine but rendered a pure white screen for anyone who cloned or deployed it. The build passed with zero errors. Nothing hinted why.
The cause: the app crashed on a missing configuration value before React even started, so no error could ever appear. The fix took 3 files and 34 lines, verified in a headless browser before and after:
| Build | What renders | What a user sees |
|---|---|---|
| Before | 0 characters | Blank white page |
| After, unconfigured | Setup screen | Exact instructions to finish setup |
| After, configured | Full app | Identical to the production site |
The fix was contributed back to the project as a public pull request: see the code. Read the full breakdown in the blank screen fix guide.
How it works
- 1. Send it. Email me a GitHub link or zip export and one line about the problem.
- 2. Free diagnosis. I run your app in a clean room and reply with what is actually broken and whether it is fixable. If it is not worth fixing, I say so. You pay nothing for a shrug.
- 3. The rescue. If you want the fix, I fix it, test it, and send it back with a plain English note. Basic and Standard turn around in 24 hours.
Paid diagnosis: $5, self-serve, results in minutes
The free diagnosis above posts its report on a public GitHub issue. If you would rather keep the report private, or you want to run the check from your own tools or agent, the same engine runs as a pay-per-run Apify Actor. Paste your repo URL, pay $5, and the full ranked report lands in your Apify account in minutes: install, build, and a real render check, with the exact blocker named.

Common questions
Which tools do you support?
Lovable, Bolt, v0, Base44, Replit, Cursor, Claude Code, and generally any React, Next.js, Python, or Node project an AI helped write.
What if you can't fix it?
Then you don't pay. The diagnosis is free either way, and I tell you plainly if the app is not worth rescuing.
Will you rebuild my whole app?
These packages are for fixing and finishing, not rebuilds. If you need a bigger scope, email me and I will quote it.
Is my code safe?
Yes. Your code runs in an isolated environment, is used only to fix your app, and access is removed after delivery.
