Search Shopify's Global Catalog

Filter by region, shipping, category, colour, size, gender, condition and price, then search Shopify's cross-merchant Global Catalog for a product. See who sells a match and at what price. It doesn't buy, hold a cart, or check anyone out.

What this tool does

Search Shopify's Global Catalog with the same filters Shopify itself exposes

Pricing competitively against other Shopify stores is hard without knowing what they charge, and a plain keyword search is too blunt to compare like-for-like. This tool searches Shopify's cross-merchant Global Catalog (the same data layer AI shopping agents use to recommend products) with the full filter set Shopify's own Catalog console exposes - region, shipping origin and destination, category, colour, size, gender, condition and stock status - and returns every eligible Shopify merchant selling a matching product, with their price and stock status. It shows who sells something and at what price. It doesn't buy, hold a cart, or check anyone out.

How to use it

Search, filter, and read the spread

  1. 1Paste a product name (e.g. 'Stanley Quencher 40oz tumbler') or a Shopify product URL.
  2. 2Optionally narrow with Region (buyer country, ships to, ships from), Attributes (categories, colour, size, target gender, condition) or Listing (in stock only, min/max price). Every filter starts unset - an untouched search is unfiltered.
  3. 3Click Search the catalog. The query hits Shopify's Global Catalog and returns matches sorted by price ascending, up to the result count you chose.
  4. 4Read the price stats: lowest, median, highest. The spread tells you whether the market has agreed on a price or whether it's still finding equilibrium.
  5. 5Scan the merchant list. Each row shows the shop name, product title at that shop, current price, and stock status. Click View to verify on the merchant's storefront.
  6. 6If a filter name or value Shopify doesn't recognise slips through, it's surfaced verbatim in a 'Notes from Shopify' panel above the results - never silently dropped.

Merchant tips

Reading the result honestly

A wide price spread (>50%) is usually a sign of mixed inventory - some listings are knockoffs, some are bundles, some are the genuine product. Click through and verify before pricing reactively.
The lowest-priced listing is sometimes a bot, a dropshipper with no inventory, or an out-of-stock item. The median price is a more honest comparison point than the lowest.
If your price is at the median or below, you're competitively positioned. If you're at or above the highest, you'd better have a strong differentiation story (faster shipping, bundle, customer service tier).
Categories and attribute values have to roughly match Shopify's own product taxonomy. A category that doesn't exist in the taxonomy just returns zero matches with no error - if a filtered search comes back empty, try loosening it before assuming nobody else sells the product.
Not every product appears in Shopify's cross-merchant Catalog yet. Stores are added gradually - if you find zero matches for a popular product, it doesn't mean nobody else sells it.
Use this for new SKU launches. Before you set a price, check what 5-10 other Shopify merchants charge for the same product. Pricing in the median window prevents day-one race-to-the-bottom dynamics.

When to reach for this

When to reach for this

New SKU launch

Set initial pricing based on real cross-merchant data, not gut feel. Avoid pricing too high (zero conversions) or too low (instant margin compression).

Quarterly pricing review

Audit your top 20 SKUs. Anything where you're 20%+ above the median is at risk of cart abandonment when shoppers comparison-shop.

Reactive pricing decisions

A customer just emailed 'Store X is selling this for less'. Look it up, filtered to the same region and condition - is the customer right, or are they comparing to a different SKU / bundle / market?

What you get out

Match list + 3-stat price summary (lowest / median / highest)

A 3-stat price grid (lowest, median, highest USD), a 2-3 sentence merchant-facing summary of where the market sits, a per-merchant table showing shop name, product title at that shop, current price, currency, stock status, and a direct link to verify on the merchant's storefront - plus any notes Shopify attached to the search (an ignored filter, an FX-converted price range). 3 searches per IP per day on the free tier (cross-merchant queries are heavier than per-merchant queries).

Frequently asked questions

What does the product lookup actually find?
It finds which other Shopify stores list the same product and what they charge, so you can see where a product is already being sold and at what price.
Can I use it to check whether a product is saturated?
That is the common use. A product listed by many stores at similar prices is a crowded market, and the lookup shows you that in one view.
Does it cover stores that are not on Shopify?
No. The lookup is Shopify-wide, so a marketplace or a non-Shopify retailer will not appear.
Are the prices live?
They are read when you run the lookup, from the public product pages. A store that changes price an hour later will not match what you saw.
