TL;DR - Oribi’s tracking code will not affect your site’s performance or loading time.
Performance/Loading Time – Your Oribi tracking code was designed to not impact the performance of any page you embed it on. We achieve this by loading our script asynchronously (i.e. our script only starts when your site finishes loading).
Script Size – The script is minimal in size — 29kb to be precise. This is probably smaller than any image on your website.
Browser Support – Your tracking code runs perfectly on pretty much any browser out there: both iOS and Android device browsers, Opera, Chrome, Firefox, and Internet Explorer (as far back as IE7).
