Does anyone have a tool or site recommendation to test how an AGOL web app would render in different internet browsers (e.g. Firefox, Chrome, IE, Edge, Safari, Opera, etc.)? I tried using the site browsershots.org, just to get some basic screenshots, but I kept getting a '404 error' from their service, so I'm looking to see what other options might be available (if any), and of course if they are free! Thanks in advance!
