The moment your prototype hits production: what actually breaks

Why Your AI-Built App Stops Working at Real Scale You ship a Lovable app on Friday. It works beautifully in the builder. By Wednesday, when you have actual users, everything changes. The database starts choking. Your builder's preview environment wasn't built for concurrent connections. You realize the connection pooling is set for one person, not fifty. The builder's infrastructure is optimized for iteration, not production load. Here's what actually happens: AI builders give you velocity. They're phenomenal at that. But they're not optimized for what comes next.
