Bolt.new is an AI tool that turns a written request into a working website, web app or mobile app, all inside your web browser.
In plain words
You type what you want, and large language models turn that request into code for a real project. There is nothing to install: the whole development setup runs in the browser. Beginners can just prompt, while developers can open the code and edit it by hand. Bolt can also publish the result online, and its cloud service adds hosting and databases. It is made by StackBlitz, the company whose WebContainers technology runs Node.js inside a browser.
A quick example
Imagine a small bakery wants an online order page. The owner describes it to Bolt, which builds the pages and the code. The owner tweaks the colours by asking again, then publishes the site to share its link with customers.
Where you'll meet it
- Marketing sites, portfolios and online stores.
- Dashboards and internal tools built quickly from a prompt.
