Shopify & WooCommerce Product Scraper + Price Change Monitor

Export every product, variant, price and stock status from any Shopify or WooCommerce store, or schedule it to tell you only what changed. One Actor, both platforms, detected automatically. No browser, no login, no API keys.

Two modes

Mode	What you get	You pay for
All products	The full catalogue: one row per product with every variant, price, compare-at (was) price, stock status, images, tags, vendor and categories.	Each product row
Changes only (monitor)	Run it on a schedule. Each run compares the catalogue with the previous run and outputs only products that are new, removed, cheaper, dearer, out of stock or back in stock, with old and new values and % change.	A tiny fee per product checked, plus each change found

Most price monitors charge you for every row on every run, even when nothing moved. In Changes only mode a quiet day costs almost nothing.

Use cases

• Competitor price tracking for e-commerce brands and agencies: daily alerts when a rival cuts prices or launches a product.
• Stock and restock alerts: know when a product sells out or comes back.
• Catalogue export for analysis, product research, migrations or feeding a spreadsheet / BI tool.
• Sale detection: every row shows onSale and the compare-at price, so you can filter discounted items.

Connect the dataset to Slack, email, Google Sheets, Make or Zapier with Apify integrations to get alerts.

Input

{
  "startUrls": [{ "url": "https://www.allbirds.co.uk" }, { "url": "https://www.example-shop.co.uk/collections/sale" }],
  "mode": "changes",
  "maxProductsPerStore": 1000,
  "monitorName": "competitors"
}

• Pass a store's homepage. For Shopify you can pass a collection URL to read just that collection.
• Changes only: the first run saves a baseline (no change rows). Schedule the Actor (e.g. daily) with the same monitorName and every later run reports changes. Snapshots live in a key-value store called shop-product-monitor-state in your own account.

Output (one row per product, abridged)

{
  "store": "https://www.beardbrand.com",
  "platform": "shopify",
  "title": "Beard Oil Set",
  "url": "https://www.beardbrand.com/products/beard-oil-set",
  "currency": "USD",
  "priceMin": 122.0,
  "priceMax": 162.0,
  "compareAtPriceMax": 216.0,
  "onSale": true,
  "available": true,
  "variantCount": 2,
  "variants": [{ "variantId": "62365517971826", "title": "1.7 fl oz.", "sku": null, "price": 122.0, "compareAtPrice": 166.0, "available": true }],
  "changeType": "price_drop",
  "changes": [{ "field": "priceMin", "old": 139.0, "new": 122.0, "changePercent": -12.23 }],
  "checkedAt": "2026-10-25T11:00:00+00:00"
}

changeType is one of new, removed, price_drop, price_rise, price_change, out_of_stock, back_in_stock, updated (and baseline / unchanged in All products mode). A per-store run summary, including any store that couldn't be read and why, is saved as OUTPUT in the run's key-value store.

How it works and what it respects

• Reads only the public product feeds the platforms serve to every visitor: Shopify's /products.json and the WooCommerce Store API (/wp-json/wc/store/v1/products). No HTML scraping, no checkout, no customer or personal data.
• Obeys robots.txt and identifies itself honestly in its user agent. One request at a time per store, with a pause between pages and back-off on rate limits.
• Stores that block automated access are skipped and reported, not forced.

Limits

• Shopify's public feed serves up to 25,000 products per store (or per collection).
• WooCommerce: per-variation prices and stock for variable products aren't in the public feed; the product's price range and overall stock status are.
• Shopify's feed has no currency field; the Actor reads it from the store's public /meta.json where available.
• Headless or custom storefronts that disable these feeds aren't supported.

Pricing (pay per event)

• Product (All products mode): $0.0008 per product, i.e. $0.80 per 1,000 products.
• Product checked (Changes only): $0.0001 per product compared, i.e. $0.10 per 1,000.
• Product change (Changes only): $0.003 per change reported.

Example: monitoring 5 stores with 500 products each, daily, with ~20 changes a day costs about $0.31/day.
