Bolt.new

Bolt.new is a browser-based AI app builder by StackBlitz that generates, runs, and deploys full-stack web applications from a single prompt. It uses an in-browser development environment powered by WebContainers technology, meaning your code runs entirely in the browser — no server-side containers, no waiting for cloud VMs to spin up.

• Instant full-stack apps — describe your app and get a working project with frontend, backend, and database code in seconds
• Live preview — see your app running in real time as the AI generates code, with hot-reload on every change
• Iterative building — chat to add features, fix bugs, change styling, and modify functionality
• Framework support — generates projects in Next.js, React, Astro, Vue, Svelte, and more
• One-click deploy — publish to Netlify or download the project to continue development locally

Non-developers, product managers, and rapid prototypers use Bolt.new to go from idea to working demo in minutes. Technical users find it valuable for quickly scaffolding projects, testing ideas, and building internal tools without setting up a local development environment.

Because everything runs in-browser via WebContainers, Bolt.new is fast and private — your code is not sent to remote servers for execution. You can also self-host the open-source version.

1. Visit bolt.new and sign in with a GitHub or Google account.
2. Type a description of the app you want to build in the prompt box. Be specific about features, pages, and functionality — e.g., “Build a task management app with drag-and-drop kanban boards, user auth, and a dark mode toggle.”
3. Bolt generates the full project and shows a live preview. Use the chat to iterate: “Add a due date field to tasks” or “Make the sidebar collapsible.”
