Site Spy — Track Website Changes Automatically

Know the moment any webpage changes. Site Spy monitors the sites you care about and shows you exactly what was added or removed — with visual diffs.

Use the extension or the web dashboard — your choice. Manage watches from the browser toolbar, or from the full dashboard on any device.
