Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureProduct listings go incomplete as a catalog grows — images never uploaded, descriptions left thin, tags and categories skipped. CatalogCheck scans your catalog and flags every gap: missing or low-quality images, weak descriptions, short titles, missing tags, product types, categories, and duplicate SKUs. Pro adds SEO checks for missing and duplicate meta titles.
Preflight Product Feed Checker scans your Shopify catalog for product data issues before they affect product feeds, Google Shopping, or ads. It flags missing GTINs or barcodes, missing images, invalid prices, out-of-stock active products, draft products, and other feed risks. Use the review queue to open affected products, fix issues in Shopify, or ignore intentional warnings.
- Scan your full catalog for 8 different product quality gaps in one pass.
- Export every flagged product as a CSV and fix at your convenience.
- Read-only by design — CatalogCheck never edits or changes your products.
- Run a preflight review before sending ad traffic.
- Find draft products, missing images, stock, price, and barcode issues.
- Use a focused review queue to fix or mark issues as okay.
- Open affected products directly in Shopify.

FAQ
CatalogCheck and Preflight Product Feed Checker: common questions
- Is CatalogCheck or Preflight Product Feed Checker cheaper?

- What features does each app list that the other doesn’t?
- CatalogCheck lists 1 the others don’t mention, such as Custom reports. A feature missing from a listing may still be supported; this compares what each App Store listing says.
- Where does this comparison’s data come from?
- Shoplist crawls Shopify storefronts to detect which apps each store runs, and reads each app’s Shopify App Store listing for reviews, pricing, features and integrations. Store counts are as of Oct 13, 2026; estimated figures are labeled.
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.
