Migrate away from Base44?

Let me start by saying im completely new to this, no idea how to code, just had a idea and ran with it. Simple time/job tracker since there's only 1 on the market for my industry and it was executed poorly. It started out really well. I used manus at first and wasn't getting the results i expected and decided to start over and try out base. I like how i can use chatgpt to bring my thoughts into a proper prompt, and base44 creates it. I thought it was going smooth and after upgrading to builders i was damn near completely finished. frontend/backend done, auth, stripe hooks, everything was working in preview and published url within days, app store guidelines passed with flying colors and i built the apk file to test. Other than a few minor UI issues, export and subscription management buttons inop, app was functional. chatgpt wrote an exact prompt of the ui issues for base44 and thats where the headaches began. Base44 turned a simple slider fix into completely breaking the app. I have spent every night the past week and roughly 300 credits, trying to get back to where i was, im going in circles at this point fixing the same issues for it to break a few prompts down the line.

I have now read many posts of people having the same issues and scaling concerns, so while id hate to start over i think now would be a good time especially for future growth in question. Where would be a good platform to move the project to that still has the "easy" ai assistance. How difficult would the migration be? would i have to start completely from scratch, or mainly just backend stuff?
