Shopify Price & Stock Checker: Competitor Products (Free)

Check a competitor's online store in a minute - for free. Paste one or more store URLs. The Actor detects the e-commerce platform, reads a sample of products spread over the whole catalog and gives you:

• prices and sale prices of the sampled products, with the discount %
• in-stock / out-of-stock status per product
• the store's price range, share of products on sale and share in stock
• the platform (Shopify, WooCommerce, T-Soft, ikas, IdeaSoft, OpenCart, GoldenPlanet) and catalog size
• whether the store's units in stock and units sold can be tracked, with a ready input for the tracker

Want the competitor's units in stock and units sold?

This free checker tells you whether a store publishes exact stock counts - not the counts themselves. Tracking them is what Competitor Stock Tracker does:

• exact units in stock for every product and variant
• estimated units sold and revenue per product between runs
• sell-outs, restocks (with units added) and price changes
• an Excel competitor report for the last 7 and 30 days: top sellers, best-selling categories, price moves, sell-outs

Every result of this checker includes trackerInput - paste it into Competitor Stock Tracker, schedule it daily, done.

What you get

One row per store. The Result per store table in the Output tab shows it at a glance.

Stores to check	Home page URLs, up to 10 per run
Products to sample per store	10 by default (at most 30), spread over the whole catalog
Proxy	Datacenter proxy is enough for most stores

Cost

The Actor itself is free - you only pay the small Apify platform usage of the run (a check of a few stores typically costs well under one cent and fits in Apify's free monthly credit).

FAQ

Why are stock counts not shown? The checker is a quick, free look at a store. Units in stock - and the units sold you get by comparing them over time - come from Competitor Stock Tracker.

Can I use it to scrape a whole catalog for free? No - it samples at most 30 products per store and 10 stores per run. For full catalogs, prices and stock over time, use the tracker.

Why is a Shopify store unreadable? Some large brands use a headless (custom) storefront instead of a Shopify theme; these are not supported yet. Blocked pages are retried with a new proxy session; if they keep failing, try residential proxy.

Does it log in or use private APIs? No. It reads only what any visitor's browser receives: public product pages, sitemaps and public storefront APIs. No personal data is collected.

Is it legal? It reads publicly available product information. You are responsible for how you use it: respect the websites' terms of service and the laws that apply to you.
