Should I keep using Lovable for a growing app or move to Cursor?

Keep Lovable for screens, use Cursor or Claude Code for logic and fixes, on the same repo. The export is a normal React app; the getting-lost part is fixed by a CONTEXT.md and a lib/index.ts map. What you should not do is keep asking Lovable to fix bugs in code it already generated wrongly; it will regenerate the whole screen each time.
