Cuprite is a driver for Capybara that uses Ferrum — a minimal-dependency pure-Ruby driver for running headless Google Chrome instances.

Because Ferrum employs Chrome's native DevTools Protocol (CDP), it doesn't need anything special in order to operate Chrome or Chromium in headless mode, unlike some alternative solutions.
