Browser Bridge (BBX) is a powerful Chrome extension designed to create a local bridge between your coding agent and an open browser tab. It offers structured access to the Document Object Model (DOM), styles, console logs, network requests, and browser storage, enabling developers to efficiently debug and interact with web pages in real-time. With features like reversible CSS and DOM patches, users can visually confirm changes without the need for screenshots or raw HTML dumps.

The extension supports various AI coding agents that utilize the Model Context Protocol (MCP) and facilitates seamless communication through a native messaging channel. Users can query the DOM, read computed styles, evaluate JavaScript, and perform actions like clicking or submitting forms directly within the page context. The extension prioritizes privacy by ensuring all data remains local, making it an invaluable tool for developers looking to troubleshoot and optimize their web applications.
