The record

Purpose: Ferrum is a high-level Ruby API for controlling Chrome.
Protocol: It connects to Chrome through the Chrome DevTools Protocol without a Selenium, WebDriver, or ChromeDriver dependency.
Browser modes: Ferrum runs headless by default and can be configured to run headfully.
Requirements: The documentation says Ferrum requires Ruby and Chrome or Chromium, and the browser binary must be available on PATH or set with BROWSER_PATH.
Browser automation: Ferrum supports page navigation, CSS and XPath element finding, and mouse and keyboard input.
Page capture: Its capture methods can save or return screenshots, PDFs, and MHTML.
JavaScript: The documentation provides methods to evaluate JavaScript expressions and execute JavaScript in a page.
Thread safety: The documentation describes Ferrum as fully thread-safe and shows pages and browser contexts being used across threads.
Proxy support: Ferrum accepts proxy settings for a browser or for pages created in separate contexts.
Integrations: The project identifies Cuprite as a Capybara driver based on Ferrum and Vessel as a web crawling framework based on Ferrum and Mechanize.
License: The Ferrum gem is available as open source under the MIT License.
Support: The documentation says bug reports and pull requests are welcome on GitHub.
Linux browser setup: The documentation advises downloading Chrome or Chromium from its official source because it says there is no official Chrome or Chromium package for Linux.
