Bolt.new by StackBlitz is one of the most popular browser-based AI app builders. You describe what you want, and it generates a working app with live preview in seconds. But it has real limitations: the token system can run dry mid-project, complex multi-page apps get messy, and backend capabilities are limited.
If you have hit Bolt's ceiling or want to evaluate alternatives before committing, here are seven tools we tested head-to-head. Each one approaches AI app building differently. We ranked them by how well they serve the same use case: going from idea to working app as fast as possible.
