Ferrum
A high-level Ruby API for controlling Chrome/Chromium via the Chrome DevTools Protocol without Selenium dependencies.
What is Ferrum?
Ferrum is a Ruby library that provides a high-level API for controlling Chrome and Chromium browsers. It enables browser automation, testing, and web scraping by communicating directly with the browser via the Chrome DevTools Protocol without requiring Selenium or WebDriver dependencies.
Ruby developers who need browser automation for testing, web scraping, or interacting with JavaScript-heavy applications, particularly those who want direct access to Chrome's capabilities beyond WebDriver limitations.
Developers choose Ferrum for its clean Ruby API, direct CDP integration that unlocks Chrome-specific features, and elimination of Selenium/WebDriver overhead, making it faster and more capable for Chrome/Chromium automation.
