Overview
Bolt.new is StackBlitz's AI-powered full-stack development environment that runs entirely in your browser. Using WebContainers technology, it creates a complete Node.js environment without any local setup - you describe what you want to build, and Bolt generates, runs, and iterates on your application in real-time. Unlike local-first tools, everything happens in the browser: npm installs, dev servers, and file editing. This makes it ideal for quick prototypes, demos, and getting from idea to working app in minutes without touching a terminal.
