So when configuring Capybara, I'm using ignore_default_browser_options, and only re-use this DEFAULT_OPTIONS and exclude the key I don't want Capybara::Cuprite::Driver.new( app, { ignore_default_browser_options: true, window_size: [1200, 800], browser_options: { 'no-sandbox': nil }.merge(Ferrum::Browser::Options::Chrome::DEFAULT_OPTIONS.except( "disable-features", "disable-translate", "headless" )), headless: false, } )

As simple as Puppeteer, though even simpler.

A lot of projects leveraging CDP appeared since then, including the most well-known one—Puppeteer, a browser automation library for Node.js. What about the Ruby world? Ferrum, a CDP library for Ruby, although being a pretty young one, provides a comparable to Puppeteer experience. And, what’s more important for us, it ships with a companion project called Cuprite—a pure Ruby Capybara driver using CDP.
