What we fix

Where AI-built apps break

  • 01

    Sign-in that loops or lets the wrong people in

    Users bounced back to sign-in, or let into pages they shouldn’t see, checked with a test account in Supabase Auth or Firebase Auth.

  • 02

    Data anyone can read, or nobody can

    Row-level security that is off, policies that trust user_metadata, and Supabase tables created after October 30, 2026 that need explicit grants.

    Supabase RLS fixes

  • 03

    Stripe takes the money, the account stays locked

    Webhooks that are missed or never verified, so a paid customer never gets access.

  • 04

    Secrets exposed in the front end

    Service-role and API secret keys in front-end code, flagged in the Launch Check and rated by severity.

  • 05

    Works in the preview, fails after deploy

    Environment variables, build settings and redirects that differ between the builder’s preview and your host.

  • 06

    One bug you can already name

    A single reproducible bug, diagnosed and fixed as a pull request with a regression test.

    App Fix Ticket

Running in production

Free checkers we built and run

App369 built these checkers and runs them on app369.com. Each reads only what you paste. The paid work goes further and confirms every issue against your running app.

  • Supabase RLS policy checker

    Reads a migration and flags policies that let users see or change rows they shouldn’t.

  • Supabase October 30 grants checker

    Finds tables created after October 30, 2026 that need an explicit grant before supabase-js can reach them.

  • Firebase Security Rules checker

    Flags rules that let one user read or edit another customer’s data.

Questions

Before you start

Do I need the Launch Check or the App Fix Ticket?

The App Fix Ticket is for one known bug. The Launch Check is for an app that is about to meet real users and needs the whole thing checked: sign-in, data access, payments and deploys.

What does the Launch Check report look like?

The Launch Check is a written check of your whole app. Each issue found is rated critical, high, medium or low, with where it is and how it was confirmed, plus a fixed price to fix the worst problems (the Rescue Sprint). No issues worth fixing, no charge. If the Launch Check finds nothing rated medium or higher, Simon refunds the full $450. You keep the report either way.

Is this the same as AI-Built App Rescue?

The Launch Check here is the same whole-app check as AI-Built App Rescue. This page helps you choose between it and an App Fix Ticket for one bug.

Will you rewrite my app?

No. The goal is to keep what works and fix what doesn’t. If the Check shows a rebuild would cost less, the report says so.

What access do you need?

Read-only: a repo invite or a zipped project, a test login, and your database structure, meaning the supabase/migrations folder or a schema export with no user data, or Viewer access for Firebase.

I’m not technical. Can I still do this?

Yes. Send the app link and a screen recording of what breaks, and you’ll get back in writing exactly what access is needed. Everything happens by email.
