Intro

Bolt.new is an AI-powered development environment by StackBlitz that generates, runs, and deploys full-stack web applications entirely in the browser with 15,000+ GitHub stars. Describe what you want in plain English and watch it scaffold the project, write code, install packages, and spin up a live preview — all without a local dev environment. Built on WebContainers technology, everything runs in-browser including Node.js and the file system. Best for rapid prototyping, MVPs, and developers who want to go from idea to deployed app in minutes. Works with: React, Next.js, Vue, Svelte, Astro, and more. Setup time: instant (web-based).

How It Works

1. Describe Your App

"Build a recipe sharing platform with:
- User registration and login
- Recipe creation with photo upload
- Search by ingredient
- Rating and reviews
- Responsive design with Tailwind"

2. Watch It Build

Bolt generates the full project in real-time:

  • Scaffolds the project structure
  • Writes React/Next.js components
  • Sets up API routes
  • Configures Tailwind styling
  • Installs npm packages
  • Starts the dev server

3. Live Preview

See your app running immediately in the browser preview panel. No npm install, no npm run dev — it just works.

4. Iterate Naturally

"Add a favorites system where users can save recipes"
"Make the search results show a thumbnail grid"
"Add pagination to the recipe list"

5. Deploy

One-click deploy to Netlify, Vercel, or Cloudflare Pages.
