Visualping is a Chrome extension that allows users to monitor websites for changes. It alerts users via email when it detects any changes in the content of a webpage. Unlike other monitoring services, Visualping is unique in that it monitors pages visually rather than based on the HTML markup. This versatile service can be used for competition monitoring, price checks, ticket availability tracking, and more. Users have the option to monitor the entire website or select a specific area of a webpage to monitor.
