Is there build-in way to detect user agent inside a template?

Question

Is there build-in Twig way to detect user agent and user IP if website is powered by Drupal 8.x ?

Something like app.request.headers.get('User-Agent')

I mean without adding custom Twig function on PHP

You can try using Browser detect module: https://www.drupal.org/project/browser_detect
