Deploying is one click, which is exactly why it is worth having a check in front of it. Before any app goes live, on every plan, Breezify runs two scans over the code it is about to ship. Both run locally on the files already in memory, so they add no cost, use no credits, and call no AI model.
The first is called App Doctor, and it looks for the ways a generated app is simply broken: an import of a file that was never written, a component used in the markup that nothing defines, or a request to an API route that does not exist. Each of those produces a blank page or a button that does nothing, and the usual way of finding out is deploying, noticing, and paying for another generation to fix it. App Doctor tells you first.
The second is a security scan, and it looks for the two ways a generated app can accidentally publish its owner's credentials. One is a secret named with a prefix that bundlers copy into the JavaScript every visitor downloads. The other is a live key hardcoded into a client-side file. It recognizes the formats of common credentials, including Stripe secret keys, AI provider keys, GitHub and Slack tokens, and AWS access keys.
Both checks are advisory. They show you a note and never block your deploy, because you know your app better than a scanner does. They are also designed to stay quiet unless they are sure. A scanner that cries wolf gets ignored, and then the one warning that matters gets ignored along with it, so every rule here stays silent whenever it cannot be certain.
If a scan does flag something, the fix is usually a short refine in the chat, and the warning tells you what to ask for. Move the key into the app's Secrets and call it from server-side code, or add the missing file, and deploy again. Deploying itself still costs nothing.
