Chrome DevTools Protocol (CDP)

The Chrome DevTools Protocol (CDP) is a set of APIs that allows developers to interact programmatically with the Chrome browser for debugging, automation, and testing. It enables tools to control and inspect web pages—such as navigating, modifying DOM elements, capturing network activity, and analyzing performance—by sending and receiving structured messages. Think of it as a communication bridge between software tools and Chrome, providing deep access to browser internals to improve web development efficiency and automation capabilities.
