I'm a developer, and I've been trying to use AI to vibe code apps for two years. This is the first time I'm able to vibe code an app without major manual interventions at every step. Not saying it's perfect, or that I'd necessarily trust it without human review, but I did vibe code an entire production-ready iOS/Android/web app that accepts payments in less than 24 hours and barely had to manually intervene at all, besides telling it what I wanted to do next.
