What is Bolt.new?
What is Bolt.new?
Bolt.new is StackBlitz's AI full-stack web application builder that can generate, run, and deploy complete web applications from a single text prompt — all within the browser. Powered by WebContainers technology that runs Node.js natively in the browser, Bolt.new doesn't just generate code but actually executes it, installs dependencies, and shows a live running preview in real time.
From Prompt to Running App
What makes Bolt.new distinctive is that it builds and runs real applications, not just code snippets. Describe a web app — "a task manager with authentication and a PostgreSQL database" — and Bolt.new generates the full-stack code, installs packages via npm, runs the development server, and displays the working app. Iterations happen live, making it feel like pair programming with an AI that can actually execute code.
- Full-stack app generation from natural language
- Real in-browser Node.js execution via WebContainers
