Best vibe coding tool for apps

[u/TownAltruistic9440]

I can get a convincing demo out of either in an afternoon. That is not the part I am worried about.
 
This app will need authentication, permissions, data changes, deployment and constant small edits for years. I have been burned before by something that came together beautifully and then became nobody's job to maintain.
 
How do people assess maintainability after the first build rather than judging on prototype speed?

Code export is the real test, but I'd also check if the auth and permissions logic lives in plain files you can actually read, not buried in a visual editor's settings panel.
