OwnerLoop: Compatible Parts

Map product-to-part relationships, show compatible items, and make them searchable for staff. OwnerLoop helps stores whose products need replacement parts, accessories, or consumables over time. Map each product to the items that fit, manage those relationships centrally, and use them across your storefront and staff workflows. Show compatible items in storefront blocks with direct add-to-cart, promote parts across your theme, and give staff a searchable compatibility lookup. Update mappings as your catalog changes.

This app's listing is still live, but it recently dropped out of Shopify's App Store search index.
