Overview

Bolt.new combines StackBlitz WebContainers with LLM AI to let you prompt, build, and deploy full-stack web apps without leaving the browser. It supports Node.js, npm packages, and popular frameworks. The entire dev environment runs client-side using WebContainers — no server-side execution needed.

Key Features

  • Browser-based full-stack development — no local setup
  • AI-assisted code generation and editing via LLM
  • Instant preview with hot module replacement
  • npm package installation within the browser
  • One-click deployment to Netlify

How It Works

Bolt uses StackBlitz WebContainers to run a full Node.js environment in your browser. When you describe what you want, the LLM generates the code, installs dependencies, and shows you a live preview. You can iterate by chatting with the AI or editing code directly in the built-in editor.
