Read-only Shopify catalog protection

Catch catalog mistakes before customers do.

Quantlock Catalog Alerts audits prices, SKUs, barcodes, images, and compare-at prices—without permission to edit your products.

Install and open Quantlock Catalog Alerts only from a Shopify-owned app page or Shopify Admin.

• Complete Free audit. See every current finding and recheck weekly.
• Low-noise incidents. Pro groups related price changes instead of sending alert floods.
• Read-only trust. Quantlock can detect a problem, but can never create one by editing your catalog.
