Shopify Competitor Monitor

Shopify Competitor Monitor — Store Catalogs, Prices & New-Product Alerts

Extract any Shopify store's full product catalog — titles, prices, compare-at prices (automatic sale detection), variants, stock availability, publish dates, collections — then watch competitor stores on a schedule for new-product drops and price changes. No API key, no login.

What you can do

Mode	What it does	Best for
products	Full catalog of a store — title, vendor, type, tags, price range, onSale flag, in-stock variant count, publish/update dates	Competitor teardown, catalog dumps
collections	Every collection with product counts	Store structure intel
product	Single product — every variant's price/SKU/compare-at/availability	Deep-dives
watch	product_snapshot rows for a list of stores, sorted newest-first	Scheduled competitor alerts

watch is the money feature: schedule it daily/hourly on competitor stores and diff rows by productId — get alerted the moment a rival launches a product (publishedAt), drops a price, or runs a sale (onSale/compareAtMax). This is the dropshipper winning-product radar and DTC competitive-intel loop in one actor.

FAQ

How does this work without an API key? Every Shopify store exposes a public catalog feed at /products.json — the same one their themes and apps use. We read it directly.

Does it work on every Shopify store? Most. Some very large stores Cloudflare-block the endpoint; if a store returns an error row, retry with an Apify proxy enabled.

How do I detect new products? publishedAt — in watch mode rows arrive newest-first; keep seen productIds and alert on first-seen.

Can it see inventory counts? Variant-level available + inventory_quantity when the store publishes it; some stores hide exact stock.

Is it legal? We read publicly accessible catalog endpoints. Respect each store's Terms of Service.
