Twelve checks on price, stock, images and variants
Keeps its own snapshot, so an alert shows the old value
One throttled notification instead of hundreds
Read-only and free, with every check included
CatalogGuard watches your product catalogue and tells you when something has changed for the worse. Run the first scan after installing: it records its own snapshot of every product and compares each later change against it, so an alert shows the price a variant used to have, not only the one it has now. Until a product has a snapshot, its first change is recorded as the starting point rather than flagged, and a re-scan runs when you ask.
Twelve checks cover the changes that quietly cost a shop money. A price falling or rising past a threshold you set, a price under a floor you set, a price under the cost recorded for that variant, a compare-at price removed or no longer showing a saving, a product hidden, deleted or out of stock, and a lost image, description or variant set.
Alerts arrive in one list you can filter, search and review. Where a change came from an app rather than a person, you can mute it so its edits are recorded but stop raising alerts. Notifications are throttled, so a bulk import sends one message that names the rest.
The app is read-only. It reports what changed and where to correct it, and never edits anything. It is free, and every check is included.
