Shopify Price & Stock Monitor

Shopify Price & Stock Monitor tracks prices, compare-at sale prices, and public variant availability for the exact Shopify product URLs you provide. Schedule repeated checks to detect price changes, restocks, sell-outs, and new or removed variants without a Shopify login or API key.

Unofficial tool. Not affiliated with, endorsed by, or sponsored by Shopify or any monitored store.

Track Shopify prices and stock

Add up to 50 public Shopify product-page URLs. The first tracked run creates a baseline for every variant found on those pages. Later runs compare the current product data with that baseline and return a focused change feed by default.

This Actor monitors explicit product URLs only. It does not discover or scrape a store's full catalog.

Shopify product monitor input

• Product URLs: Public Shopify /products/ pages or their .js product URLs.
• Track changes: Save a baseline for future comparisons.
• Include unchanged variants: Return a complete current snapshot instead of changes only.
• Snapshot store name: Keep one watchlist's history separate from another.
• Concurrent checks: Check between 1 and 10 products at once.
• Proxy configuration: Useful when a storefront restricts cloud traffic.

Shopify price and availability data

Each result represents one product variant. Available fields include product and variant titles, vendor, SKU, options, current price, compare-at price, currency, sale status, public availability, product image, check time, and source product URL.

Change fields show whether a variant is new, changed, unchanged, removed, not found, or not checked. When a price or availability value changes, the result can also include its previous value.

Shopify competitor monitoring use cases

• Watch selected competitor products for discounts or price increases.
• Detect public restock and sell-out signals.
• Track new or removed sizes, colours, and other variants.
• Feed a spreadsheet, dashboard, or alerting workflow with scheduled checks.

Pricing

Pricing is based on successfully checked product URLs, not the number of variants returned. Failed or unavailable product checks are not successful product checks. Use the run spending limit to control the maximum cost of a watchlist.

Shopify monitor FAQ and limitations

Can it monitor a whole Shopify store? No. Provide every product page you want to monitor.

Is availability an inventory quantity? No. It is the storefront's public availability signal, not a guaranteed stock count or fulfilment promise.

Are changes detected in real time? No. Changes are detected between runs, so schedule checks at the frequency your use case needs.

Password-protected products, non-Shopify pages, removed products, or storefronts that block access may not return usable data. Prices can also vary by market, currency, or shopper context.
