Ferrum
A high-level Ruby API for controlling Chrome/Chromium browsers directly via the Chrome DevTools Protocol.
What is Ferrum?
Ferrum is a Ruby library that provides a high-level API to control Chrome and Chromium browsers programmatically. It connects directly via the Chrome DevTools Protocol, enabling automation, testing, and web scraping without Selenium or WebDriver dependencies. The library runs browsers headlessly by default but supports headful mode for debugging.
Ruby developers who need browser automation for testing, web scraping, or automation scripts, particularly those who want direct access to Chrome's capabilities without WebDriver overhead.
Developers choose Ferrum for its clean Ruby API, elimination of external driver dependencies, and direct access to Chrome's full CDP features that are often restricted in cross-browser automation tools.
