Hexowatch is more like a recon drone which lets you monitor any web page for changes, and you can use it to monitor how your pages display (for defacement protection or to be notified when an update has caused a visual bug) as well as use it to monitor your competitors, suppliers and just about any website.
What makes Hexowatch really powerful is how you can specify what types of changes to look for, and how frequently you want to check these. For example, you can specify to be notified when a visual change is detected (in case a recent update caused a bug), or you can be alerted only when a price is updated when new content has been published, when a website adds a new script or changes their tech stack, or get a notification when a backlink partner stops linking back to you.
All changes trigger a snapshot which is archived in the cloud for comparison and you can be notified by email or other notification channels connected when a change is detected.
