Exact problems, grouped
Blank SKUs, exact duplicate SKUs, normalized collisions, and duplicate barcodes are grouped into a repairable queue.
Read-only Shopify catalog monitoring
Catch SKU and barcode mistakes before fulfillment does.
Find blank, duplicate, and collision-prone Shopify SKUs and barcodes without giving an app permission to edit your catalog.
Check installation availabilityDirect Shopify links
See product and variant context, then open the affected variant in Shopify Admin.
No write scope
The app monitors read-only. It cannot silently rewrite identifiers or damage integrations.
Shopify App Store listing
Lige SKU Sentinel is not available for public installation yet. When Shopify publishes the listing, installation will start on the App Store.
Listing coming soon
Installation will open here when the Shopify App Store listing is ready.
Questions merchants ask
Does SKU Sentinel edit products?
No. The app requests read_products only and links each finding back to Shopify Admin so a merchant remains in control.
How many variants can it scan?
Free checks up to 500 variants. Pro checks up to 20,000 variants and adds nightly reconciliation.
What counts as a SKU collision?
Exact duplicates are errors. Values that become equal after case and whitespace normalization are shown separately as warnings.
