Common wall · My app works locally but not in production
Your app works on your computer—but not for real users.
Why an AI-built app works locally but fails after launch, what to check first, and when the problem needs a focused Ship or Rescue engagement.

Direct answer
What this wall usually means.
When an app works on your computer but fails after launch, the live version usually has different settings, service addresses, permissions, or sign-in rules. Treat it as an environment mismatch, not proof that the whole app is broken. Preserve the working version, reproduce one failing customer journey, and compare its live dependencies.
Recognize it
Symptoms that belong together.
- The home screen loads, but sign-in or the main action fails.
- The live app shows a generic error while the preview looks normal.
- Email, uploads, or outside services work only on your computer.
- A new public link behaves differently from the builder’s preview.
First checks
Gather evidence before another patch.
- 01Stop changing unrelated screens and save the version that still works locally.
- 02Write down one exact journey: what the user clicks, what should happen, and where it stops.
- 03Confirm the live app has its own approved sign-in address and private settings.
- 04Check the live error record for that exact attempt instead of asking the AI to guess.
DIY or bring in help?
Stop when the risk is larger than the clue.
A focused check is reasonable when you have a stable version and one repeatable failure. Bring in help when the app, customer impact, or safety boundary is no longer clear.
- Real users are blocked and each new fix changes a different part of the app.
- The failing journey crosses sign-in, email, payments, or customer data.
- You cannot tell which version is live or which private settings it uses.

Inside the Ship Framework
Connect + Launch
Connect verifies that identity, email, data, and outside services work as one journey. Launch then checks the same journey in the real environment with the real settings—before inviting more users.

Before you change anything.
Why does an app work locally but not after deployment?
Your computer and the live environment do not automatically share the same addresses, permissions, private settings, stored data, or sign-in approvals. A local preview can succeed with assumptions that are missing or intentionally restricted after launch.
Should I redeploy the app until it works?
No. Repeating the same launch without identifying the difference usually produces the same result and can make version history harder to follow. Reproduce one failure, gather its evidence, then change the smallest relevant setting or behavior.
Is this a Ship or Rescue problem?
Choose Ship when the app has not served real customers reliably yet. Choose Rescue when a previously working live app is now blocking users or a rushed sequence of fixes has made its state unclear.
