Bolt.new
Bolt.new is StackBlitz's AI full-stack development environment that builds, runs, and deploys complete web applications from natural language prompts entirely in the browser.
Bolt.new is a revolutionary AI-powered full-stack development platform built by StackBlitz, leveraging WebContainers technology to run a complete Node.js environment natively in the browser. Unlike code generation tools that merely output snippets, Bolt.new creates, executes, and iterates on entire web applications in real time—all without installing anything locally. You describe what you want to build, and Bolt.new scaffolds the project, installs npm packages, runs the dev server, and gives you a live preview, all in a single browser tab.
The core innovation behind Bolt.new is StackBlitz's WebContainers runtime, which runs a real Node.js environment inside the browser using WebAssembly. This means Bolt.new isn't simulating a development environment—it's actually running one. It can execute shell commands, install packages from npm, run build tools like Vite or webpack, and serve applications over localhost, all without leaving the browser or touching a server. This architecture eliminates the traditional friction of environment setup and makes true full-stack prototyping accessible to anyone.
Bolt.new supports a broad range of modern web frameworks and technologies. You can build applications with React, Vue, Svelte, Astro, Remix, or plain HTML/CSS/JavaScript. It handles backend logic too—you can create Express APIs, connect to databases, and wire up full-stack features within the same environment. The AI understands your entire project context, allowing it to make coherent multi-file changes that maintain consistency across components, routes, and configuration files.
The platform excels at rapid prototyping and validation workflows. Entrepreneurs use it to build MVPs in hours rather than days. Designers use it to create functional interactive prototypes that go beyond static mockups. Developers use it to explore new frameworks or third-party integrations without polluting their local development environments. The one-click deployment to platforms like Netlify makes the path from idea to publicly accessible URL shorter than ever before.
Bolt.new is particularly powerful for non-engineers and low-code practitioners. Because the entire workflow happens through conversation—you describe a feature, Bolt.new implements it, you review the result, and iterate—it removes the barrier of knowing how to set up a development environment. This democratizes web development in a meaningful way, enabling product managers, marketers, and entrepreneurs to build functional web tools without writing a single line of code themselves.

Frequently Asked Questions
Is Bolt.new free to use?
Bolt.new offers a free tier that includes a daily token allowance for AI generations. The free plan is sufficient for experimentation and small projects. Paid plans unlock significantly higher token limits, larger file support, and additional features like private projects and team collaboration. The pricing is consumption-based, reflecting the computational cost of running full Node.js environments in the cloud.
Do I need to know how to code to use Bolt.new?
No, Bolt.new is designed to be accessible to non-engineers. You describe what you want in plain English, and the AI builds it for you. You can iterate on features through natural conversation without writing any code. However, having some familiarity with web concepts—like what a component or API is—helps you give better prompts and understand the output. Technical users can also directly edit the generated code within the built-in editor.
What frameworks and technologies does Bolt.new support?
Bolt.new supports a broad range of modern web technologies including React, Vue.js, Svelte, Astro, Remix, Next.js, and plain HTML/CSS/JavaScript. On the backend, it supports Node.js, Express, and various database integrations. It can install any npm package, which effectively means it can work with most JavaScript and TypeScript libraries in the ecosystem.
How is Bolt.new different from other AI coding tools?
The key differentiator is that Bolt.new runs a real, full execution environment in the browser. Tools like GitHub Copilot or ChatGPT generate code you then have to run yourself. Bolt.new actually executes the code, installs dependencies, runs the server, and shows you a live preview—all in one environment. This makes the feedback loop immediate and removes all setup friction, which is especially valuable for rapid prototyping.
Can I export and continue developing Bolt.new projects locally?
Yes, you can download the entire project as a zip file or connect it to a GitHub repository. This allows you to continue development in your local IDE like VS Code, or hand off the project to a development team for further work. The exported code is standard, clean code with no proprietary lock-in—just the npm packages and frameworks you chose.
