See why a product matches an automated collection. Review each rule as PASS, FAIL, or UNKNOWN.
RuleLens explains native automated-collection membership for a selected product. It reads the collection rules returned by Shopify and labels each result PASS, FAIL, or UNKNOWN, with the values used in the comparison. RuleLens is read-only: it does not edit products or collections. Manual collections and unsupported or incomplete rules are reported as UNKNOWN. Storefront visibility can still depend on publication, Markets, themes, navigation, and other Shopify settings.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows RuleLens Collection Debugger on a store, it is there.
