Let me start with a disclaimer that I work for Atatus. Front-end monitoring is the other end of the circle, that complements production monitoring. With Atatus that is what we have done. We monitoring the front-end for both errors and performance issues - https://www.atatus.com/
Initially we planned to show the report in the web itself. Here we are trying to find actual load time of every site, so we are getting each and every resource(css, html, js, images) in the HTML, not just the main HTML. Normally every site has page load time from 3 sec to 20 sec. Since we have one main site and one or more competitor sites, it takes us sometimes more than a minute to generate a report. Thats why we choose to send a report by email.
