Whether you’re trying to score a coveted pre-order or you’re just keeping track of the news, nobody wants to sit around refreshing a web site until it changes. VisualPing is a simple service that monitors for changes to a site, and then sends you before and after screenshots once the site changes.
Change detection on web sites certainly isn’t new, but VisualPing does things a little differently by monitoring the actual visual look of a site. This means it’s great when you’re waiting around for product launches or for updates to a page that doesn’t have RSS. Simply set up the interval for it to check, how much a change you want it to watch out for, and then VisualPing does the rest.
