Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureInventory numbers go wrong quietly. A sync fails, an import loads the wrong sheet, a fulfilment double-counts, and the first sign is that a product stopped selling. Driftwatch downloads your full catalog from Shopify every night and compares it against what it recorded yesterday. It reports what changed, what went negative, and what moved in bulk, then stays silent until something else drifts.
Merchants often forget to uncheck the restock box during refunds, which silently returns sold-out or returned items to available inventory. This causes overselling, false back-in-stock alerts, and customer complaints. Stock Warden watches every refund and automatically corrects these unintended restocks, usually within seconds. It works in the background with no manual steps.

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
