title: Using headless browser in Coypu
body: <p>I've heen recently using Coypu (<a href="https://github.com/featurist/coypu" rel="nofollow noreferrer">https://github.com/featurist/coypu</a>) for some web pages automation and it's great for that, if you need UI. But I wonder if I could do it on a headless browser, afaik Copyu supports only GUI browsers out of the box and I dont see any options to set headless mode.</p>
  <p>Is it possible with default browsers or should I add some by myself (for example PhantomJS), and how could I do that?</p>
