I tested 3 AI app builders in 2026, here's what actually worked

Tested quite a few over the past months. These 3 kept coming back to my workflow:

CatDoes — best for full mobile apps with backend

Lovable — best for landing pages and simple apps

Replit — best for developers who want AI assist

What are you guys using? If I missed something good, drop it in the comments, always open to adding more to the list.
