Security and access
Preview-ready apps can still expose data, trust client-side checks, or give users permissions they should never have.
AI coding tools can get you to a working prototype quickly. This checklist helps you find the security, reliability, infrastructure, and scaling gaps that appear when real users arrive.
Generating features is only one part of launching a dependable product. These are the areas that usually need deliberate engineering before an app is ready for real customers.
Preview-ready apps can still expose data, trust client-side checks, or give users permissions they should never have.
Without structured logging, alerts, and recovery paths, the first person to report a production failure is often a customer.
Environment configuration, backups, migrations, and database limits tend to break only after the app leaves the builder preview.
Use it before launch, during technical due diligence, or as a structured audit of an app that is already live.
Verify authorization boundaries, secrets, input handling, and the controls protecting sensitive actions.
Review data constraints, backups, migrations, service limits, and backend failure behavior.
Check registration, sessions, password recovery, account lifecycle, and protected routes.
Validate payment states, webhooks, retries, duplicate events, and transaction records.
Confirm environments, domains, configuration, release processes, monitoring, and rollback plans.
Test realistic traffic, slow dependencies, caching, background work, and expensive queries.
The checks are tool-agnostic. They apply whether AI generated a small part of the codebase or nearly all of the first version.

Run the 27 checks before real users, real payments, and real data depend on your app.
