bolt.newAbout Bolt.new
Bolt.new is StackBlitz's AI-powered full-stack web development environment that generates, runs, and deploys complete applications from a single prompt. Unlike traditional code assistants, Bolt.new executes code live in the browser using WebContainers — so you can see your app running as it's being built. Built on Claude Sonnet, it generates frontend + backend + database in one go. Best for rapidly prototyping SaaS apps, landing pages, and internal tools without a development environment setup.
