# bolt.new: AI-Powered Full-Stack Web Development in the Browser

bolt.new is an AI-powered web development agent that allows you to prompt, run, edit, and deploy full-stack applications directly from your browser—no local setup required. This MCP Client integrates AI models with an in-browser development environment, giving AI agents complete control over the entire development lifecycle.

## Full-Stack Development, Browser-Native

Unlike many AI tools that only assist in code generation, bolt.new empowers AI models with full environment control. This means the AI can interact with the filesystem, manage Node.js servers, use the package manager, and operate the terminal and browser console. This capability is powered by StackBlitz’s WebContainers, enabling a comprehensive development experience directly within your browser.

With bolt.new, AI agents can:

*   Install and run npm tools and libraries, such as Vite and Next.js.
*   Run Node.js servers.
*   Interact with third-party APIs.
*   Deploy applications to production directly from chat.
*   Share work via a URL.

## AI with Environment Control

The core differentiator for bolt.new lies in its ability to grant AI models complete control over the development environment. Traditional AI assistants might generate code snippets, but bolt.new extends this to the entire application lifecycle. This includes managing the filesystem, running Node.js servers, handling package installations, and interacting with the terminal and browser console. This level of control allows AI agents to move beyond mere code suggestions to actively build, test, and deploy full-stack web applications.

## Building Your Own AI Web Dev Agent

For developers interested in extending or customizing the platform, bolt.new provides an open-source codebase. This allows you to build your own AI-powered web development agent, leveraging the same underlying architecture that powers bolt.new's in-browser capabilities. The project's GitHub repository serves as the starting point for contributing to or forking the codebase.
