> What to ask before you ship an app built with Lovable, Bolt, v0 or Bubble, with the short answer first, plus engineering notes read from the code.

Each guide answers one question a founder asks before shipping, with the short answer up front and a source for every figure.

## Questions about apps built with AI

- [Is my AI-built app leaking data?](https://thorfyn.com/en/notes/is-my-ai-built-app-leaking-data): It can be, if row level security is off on any Supabase table. Four checks, each in minutes.
- [How do I take a Lovable, Bolt or v0 app to production?](https://thorfyn.com/en/notes/lovable-bolt-v0-app-to-production): Diagnose for a week first, then harden or rebuild in stages, in your own repository and accounts.
- [Should I move my Bubble app to code?](https://thorfyn.com/en/notes/bubble-to-code-migration): When cost per user or speed stop fitting the plan. Move one part at a time, never all at once.
- [What does fixing an AI-built app cost?](https://thorfyn.com/en/notes/cost-to-fix-an-ai-built-app): From 390 USD for a written verdict in one day, then a fixed price per stage.

## Engineering notes

- [From 1,000 to 1,000,000 users: what changes](https://thorfyn.com/en/notes/from-1k-to-1m-users): Four stages, from 2 roles to 9. Which layers come in at each one and what stays the same. (data: House model, not a market average)
- [The client panel from the inside](https://thorfyn.com/en/notes/the-client-panel-from-the-inside): Two ways to approve, how a client gets in, and what the activity record refuses to change. (data: Running system)
- [The exit package: what you keep and how we check it](https://thorfyn.com/en/notes/the-exit-package): What the package holds, when it counts as out of date, how the exit test is recorded and what closing the panel does. (data: Running system)

A guide or a note is published only when the number behind it exists and its source can be pointed to.
