Picking an AI app builder for a small internal tool — how do you avoid lock-in?

How to
#1

I work at a small logistics company in Baltimore and I’ve been tasked with building an internal tool for tracking shipments and driver schedules. I don’t have a formal dev background, so I’ve been looking into AI app builders that promise to generate a working app from a description.

What worries me most is lock-in. If I build something on one of these platforms and it turns out to be the wrong fit six months from now, I don’t want to be stuck rewriting everything from scratch or paying for a tier I don’t need. I also can’t tell how much control I’d actually have over the data model versus just accepting whatever the AI generates.

I’ve seen a few comparisons of 2026 AI app builders online, but they mostly focus on features rather than what happens after you commit. For anyone who’s actually used one for a real internal tool, how did you evaluate the exit path before starting? Did you prototype on more than one platform first?

The data-model question is the one I’d settle first: I’d sketch the shipment and driver-schedule tables myself before generating anything, then see whether the builder lets me edit fields, relations and permissions by hand afterward. For the exit path, I’d test how cleanly one record set exports, and whether the generated schema or code is portable. My main worry is that a quick prototype looks fine but pins me to per-seat pricing once drivers need logins. I’ve been comparing options in this list: Best Anything Alternatives (2026). Has anyone actually migrated off one of these mid-project?
