What is a Website Change Alert?
Automatically capture visual diffs, receive instant notifications, and prove compliance when any page element moves, updates, or disappears.
A website change alert notifies you when a page no longer matches a previous screenshot or DOM snapshot. Add Screenshots helps teams track website changes by comparing scheduled captures and sending a diff summary with supporting evidence.
When a change is detected you decide how the evidence is shared:
Add Screenshots compares the latest capture to the previous version at the pixel level and checks DOM snapshots. If sections differ beyond your tolerance, an alert is triggered with before/after evidence.
Yes. Target a single component by providing a CSS selector or XPath, combine it with focus element, and limit notifications to what matters.
Create a webhook monitor and point it to your Slack, Teams, or custom endpoint. The payload contains metadata, diff status, and links to the latest screenshots so you can orchestrate follow-up actions.
Monitoring should always respect the terms of service for the websites you track and comply with local privacy or security regulations.
