It works, but it is not mine
The app runs, customers use it, and the whole thing lives inside a platform you pay every month and cannot walk away from. You want the code in a repository with your name on it.
Stuck halfway
Your app works in the demo. Now it has to work for real.
Lovable, Base44, Bolt and v0 are very good at getting you to something that runs. They were never built to hold your customers money and data. If that is the wall you just hit, the useful first step is not a quote. It is knowing exactly what you have.
