Ferrum is a Ruby library providing a clean, high-level API to control Chrome or Chromium via the Chrome DevTools Protocol (CDP), with no Selenium/WebDriver dependency. It runs headless by default and supports navigation, screenshots, JavaScript evaluation, and mouse/keyboard interaction.
Use cases
- scrape javascript-rendered websites with ruby
- take screenshots of web pages programmatically
- automate a headless chrome browser in ruby
- evaluate javascript on a page and extract results
- drive chrome via cdp without selenium
- test web apps with a real browser from ruby
When to choose
- you need a pure Ruby headless Chrome driver without Selenium/WebDriver overhead
- you want direct access to Chrome DevTools Protocol features
- you're building Ruby web scraping or browser automation on top of Chrome
When to avoid
- you need cross-browser testing beyond Chrome/Chromium
- you're not working in Ruby
- you need a Capybara driver directly - use Cuprite, which is built on Ferrum
