chrome-remote-interface is a Node.js library that provides a convenient interface for interacting with the Chrome DevTools Protocol, allowing developers to control and instrument Chromium-based browsers programmatically. The project exposes browser debugging and automation capabilities through a straightforward JavaScript API that abstracts the underlying DevTools protocol commands and events. By connecting to a running browser instance with remote debugging enabled, developers can inspect network activity, manipulate pages, capture screenshots, automate navigation, and analyze performance metrics. The library is commonly used for building browser automation scripts, testing tools, web scraping systems, and custom developer tooling that interacts directly with Chrome internals. Unlike higher-level tools such as Puppeteer, Chrome Remote Interface focuses on exposing the raw protocol in a more flexible and transparent way.
