bolt.diy is an open project from StackBlitz Labs, forked from Bolt.new. You describe the app you want, and it generates a full-stack web application that you can run, edit and deploy from the same place.
Its main draw is flexibility: you can connect whichever large language model you prefer. It is free and hosted on GitHub with a large following. It suits developers who want an AI app builder they can control and run themselves.
