When your prototype gets real users, do you stick with AI builders or move to Replit?

I tried building a quick waitlist landing page using a couple of the popular AI code generation tools.

While spinning up the UI in the browser takes literally minutes I always hit a wall the moment I need to add real backend logic handle database migrations or fix weird routing bugs manually. It feels fast at the start but messy later.

For anyone who actually scaled a prototype past day one did you keep using tools like Bolt or did you wish you had just started in a proper environment like Replit or VS Code from the beginning?
