Bolt.new

What is Bolt.new?

Bolt.new is an AI web app generator that runs inside your browser. You type a prompt like build me a habit tracker with a login, and Bolt scaffolds a full project, installs dependencies, runs the dev server and shows the result, all without you leaving the tab.

It was created by StackBlitz, the company known for WebContainers, a WebAssembly-based technology that runs Node.js in the browser. That foundation is what makes Bolt feel magical: the generated app is genuinely executing, so you can test flows, read console errors and even fix them by chatting.

Bolt's sweet spot is speed. It is a favorite for prototyping, learning and building small production apps, and the generated project can be exported to GitHub or deployed through services like Netlify when you are ready.

Key Features

• Prompt-to-app generation for full-stack JavaScript projects
• Runs Node.js in the browser via WebContainers, no install needed
• Live preview with a real terminal and console output
• Iterative chat: describe changes and Bolt applies them
• Works with React, Vue, Svelte, Next.js and more
• Export your project to GitHub
• One-click deploy options for sharing your app
• Shareable links so teammates can see the running app

How to get started

Open bolt.new, sign in and describe your app in the chat. Bolt creates the project and boots it in the preview pane, then you refine with follow-up prompts. No local setup is required, which makes it a great first AI coding experience.

• Visit bolt.new and sign in
• Type a description of the app you want
• Watch Bolt scaffold the project and run it in the preview
• Ask for changes in the chat, like restyle the dashboard
• Export to GitHub or deploy when you are happy

Use cases

• Rapid prototyping of web app ideas
• Learning web development by reading generated code
• Building internal tools and CRUD apps
• Designing landing pages with working components
• Hackathon projects built in an evening
• Teaching coding with a live, editable example

Pricing and licensing

Bolt.new is a proprietary service with a free tier that lets you try the core experience. Paid plans grant more tokens per day, faster generation and higher limits, since each chat request consumes AI tokens.

Token pricing and plan details change frequently, so the official website is the place to check current numbers. The generated code is yours to export, and StackBlitz also offers Bolt for teams and businesses with shared workspaces.

Pros and cons

The killer feature is the in-browser runtime. Because the app actually runs, you can verify behaviour, not just trust the AI, and the iteration loop of chat, test, fix is extremely tight. It is also zero setup, which lowers the barrier for complete beginners.

The limits are tied to tokens and complexity. Big prompts burn through your allowance quickly, and very large or specialized projects can hit the browser sandbox's limits. Serious production work may still need a traditional local setup eventually.
