in plain english

Bolt.new is an AI-powered web development tool that lets you describe a web application in plain English and have it built, run, and deployed, all inside your browser, with no software to install on your computer. You describe what you want (the "prompt"), and the AI generates the code, installs the necessary packages, starts a server, and lets you see and interact with the running app immediately. What sets Bolt.new apart from other AI coding assistants is that it gives the AI full control over the entire development environment, not just the ability to suggest code. This includes the file system, the package manager (the tool that installs software libraries), the server, the terminal, and the browser console. As a result, the AI can install dependencies, run the backend (server-side code), interact with external services, and even deploy a finished app to a public URL, all from within a single chat interface. It is built on StackBlitz's WebContainers technology, which runs a real development environment directly in the browser using a special sandboxed runtime. The codebase is TypeScript and uses the Anthropic AI API. It is aimed at developers, PMs, and designers who want to go from idea to working, deployed application quickly. A free tier is available, with paid plans for more usage. If you want to build your own AI-powered development agent, the underlying open-source code is available in this repository as a starting point.
