Bolt

What is Bolt?

Bolt, available at bolt.new, is an AI app builder from StackBlitz that creates full-stack web applications from a prompt. It runs a complete development environment in the browser, so it can install packages, run a dev server and show a live preview without any local setup. Bolt is aimed at founders, designers and developers who want to go from an idea to a running app quickly while still having access to the underlying code. Its distinguishing trait is the in-browser environment built on StackBlitz WebContainers, which lets the AI work with real project files and terminal output. Projects can be edited by hand, downloaded or published from the same workspace.
