What is Bolt.new?
Bolt.new is StackBlitz's AI-powered full-stack web development environment that lets you build, run, edit, and deploy complete web applications from a single text prompt — entirely in the browser with no local setup required. Unlike Lovable or v0 which generate static frontends, Bolt.new runs a full Node.js environment in the browser, meaning it can install npm packages, run servers, connect to databases, and deploy live applications. It's become one of the fastest ways to go from idea to working web app, generating complete React or Next.js applications with backend logic, APIs, and database connections.
