Bolt.new: Build Websites and Apps by Describing What You Want
What if you could start building a website or app by explaining your idea instead of setting up a development environment first? Bolt.new is an AI-powered app builder from StackBlitz that lets you describe a project in plain language, generate working code in your browser, preview the result, and keep refining it with follow-up instructions.
It can be useful for founders testing an idea, creators making a personal website, or small businesses that need a booking tool, dashboard, directory, or online store. But “AI built it” does not automatically mean the app is ready for real customers without testing.
How does Bolt.new work?
- Describe your idea. Explain who the app is for, what people should be able to do, and how you want it to look.
- Let Bolt create a first version. The builder generates the project and displays a working preview in the browser.
- Improve it in small steps. Ask for a change, test it, then continue. Bolt's Plan mode lets you think through features before modifying an existing project. Visual Edits lets you click elements and make supported text or styling changes before applying them together.
- Review and publish. You can inspect and edit the code, connect data or services where supported, and deploy when the result is ready.
Bolt's official product page describes support for full-stack web apps, including interfaces and back-end features such as authentication and databases. React, Vite, Tailwind CSS and Node.js are listed among its default technologies, though the exact stack depends on the project and your instructions.
What can you build with it?
- A landing page for a business or new product.
- A booking form or appointment-management app.
- A simple online store or product catalogue.
- A dashboard or internal business tool.
- A prototype to show potential users before investing in a larger build.
Good information should help you ask better questions, not stop asking them.
