Bolt

Also called: bolt.new, Bolt.new, StackBlitz Bolt

StackBlitz's AI app builder at bolt.new. A person describes a web app, and Bolt writes, runs and edits it in the browser, with tools for publishing it. Its official guide says you can ask for shadcn/ui when starting a project so it builds with those components.

For example: A founder asks Bolt to build a booking prototype with shadcn/ui buttons and forms, then checks the working screens before showing them to a customer.
