CatalogDelta launched on September 2, 2026. Shoplist is watching for its first storefront installs and tracking pricing in the meantime.
Apps merchants weigh against CatalogDelta, with their own detected stores and ratings.
Get alerted on first storefront installs, review spikes, pricing changes, and listing edits.
Detect risky catalog changes before content or identifier issues reach shoppers.
CatalogDelta runs deterministic, read-only checks across active products and variants. It flags missing identifiers or descriptions, unusual sale-value states, duplicate SKU or barcode values, and optional shipping-data gaps. Failed scans never clear earlier findings, and the app never edits products. Merchant-defined policies keep results focused.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows CatalogDelta on a store, it is there.
