Shopify Scraper: Products, Prices & Stock Monitor — Cartlark

Cartlark: Shopify Scraper — Products, Prices & Stock Monitor (also WooCommerce)

Every product, price, sale price and stock level of any Shopify or WooCommerce store, and an alert when they change

Paste a store URL and get its whole catalogue as clean rows: title, price range, compare-at (was) price, discount %, stock per variant, SKU, vendor, type, tags, images and link. Turn on monitor mode, schedule it, and you only get (and only pay for) what changed: price drops and rises with the % change, new products, out-of-stock and back-in-stock. Works with Shopify and WooCommerce, detected automatically. $0.80 per 1,000 products, no start fee.

▶ Try it now with a prefilled input · $0.0008 per product (a 250-product store = $0.20) · no start fee · Apify's free plan includes $5 of credit a month

Built for: e-commerce brands watching competitors' prices · dropshippers and resellers researching products · agencies auditing a client's catalogue · price-comparison and deal sites · market researchers · AI agents that need a store's live catalogue

Ready-made inputs (one click)

Job	Input	Result
Whole catalogue	{"stores": ["competitor.com"]}	Every product (up to 250; raise maxProductsPerStore for more).
One collection	{"stores": ["https://shop.com/collections/sale"]}	Just that Shopify collection.
What's on sale	{"stores": ["shop1.com", "shop2.com"], "onlyOnSale": true}	Products priced below their compare-at price, with discount %.
Product research	{"stores": ["shop.com"], "keywords": ["hoodie", "jacket"], "maxPrice": 80}	Matching products under $80.
Price & stock alerts	{"stores": ["competitor.com"], "monitor": true, "monitorKey": "competitors"}	On a schedule: only new products, price changes and stock changes.

Use cases

• Competitor price monitoring: a daily scheduled run on your competitors' stores, with a Slack or email ping when a price drops or a product sells out.
• Restock and drop alerts: know the moment a sold-out product is back or a new collection lands.
• Product research for dropshipping and resale: best sellers, price points, vendors and tags across many stores in one table.
• Catalogue audits: missing SKUs, products without images, out-of-stock items, sale prices left on by mistake.
• Feeds for comparison sites and AI agents: clean JSON with a stable shape for both platforms.

Output fields

Field	What it is
platform, store, productId, url	Where the product lives.
title, vendor, productType, tags, sku	Product details (WooCommerce: categories and tags go into tags, the first category into productType).
price, priceMax, currency	Lowest and highest variant price, in the store's currency.
compareAtPrice, onSale, discountPercent	The "was" price and the discount when the product is on sale.
available, variantsAvailable, variantCount	In stock at all, how many variants are in stock, how many variants exist.
variants[]	Each variant: id, title, SKU, price, compare-at price, in stock, options (size/colour). Shopify.
image, imageCount	Main image URL and number of images.
rating, reviewCount	WooCommerce product rating, when the store shows one.
description	Plain text, when includeDescription is on.
createdAt, publishedAt, updatedAt, scrapedAt	Dates (Shopify gives all three).
change, previousPrice, priceChange, priceChangePercent, previousAvailable	Monitor mode only: new, price, compare_at_price, out_of_stock, back_in_stock or variants.

A run summary per store (platform found, products scanned and delivered, and the reason when a store could not be read) is saved as the OUTPUT record.

Input

Field	What it does
stores	Store domains or URLs. A Shopify /collections/<name> URL limits the run to that collection.
maxProductsPerStore	Default 250. In monitor mode: how many products per store are watched.
keywords, minPrice, maxPrice, onlyAvailable, onlyOnSale	Filters. Filtered-out products are free.
includeVariants, includeDescription	Row detail.
platform	auto (default), shopify or woocommerce.
monitor, monitorKey	Only changes since the last monitor run with the same watchlist.
proxyConfiguration	Optional, for stores that rate-limit.

Run it on a schedule (price and stock alerts)

1. Open the Actor, set {"stores": ["competitor-a.com", "competitor-b.com"], "monitor": true, "monitorKey": "competitors"} and save it as a task.
2. Schedules → Create: daily at 07:00 (cron 0 7 * * *), pointing at the task.
3. Add an integration on the task: Slack, email or a webhook "when the run succeeds". The first run records the catalogue; every later run returns only what changed, so a quiet day costs almost nothing.

Integrations

• Google Sheets / Make / Zapier / n8n: use the Apify app or node and map the dataset fields (title, price, compareAtPrice, available, change).
• API (curl):

  curl -X POST "https://api.apify.com/v2/acts/cybermax~shopify-scraper/run-sync-get-dataset-items?token=YOUR_TOKEN" \
    -H "Content-Type: application/json" -d '{"stores": ["https://www.allbirds.com"], "maxProductsPerStore": 20}'
  

• Python: ApifyClient(token).actor("cybermax/shopify-scraper").call(run_input={"stores": ["allbirds.com"]})
• AI agents (MCP): add cybermax/shopify-scraper to the Apify MCP server (https://mcp.apify.com?actors=cybermax/shopify-scraper) so Claude, Cursor or any MCP client can ask "what does this store sell, and at what price?".

FAQ

Which stores work? Any Shopify store and any WooCommerce store that has the standard public catalogue switched on (most do). Password-protected stores, stores that disable these endpoints, and stores whose robots.txt disallows them are skipped, and the summary says why. Other platforms (Wix, BigCommerce, Magento) are not supported.

Is it legal? Cartlark reads only the public product catalogue a storefront serves to every visitor, the same data shown on its product pages, and it follows each store's robots.txt. It collects no customer or personal data. Use the data in line with the laws that apply to you.

Why not write my own script? You can; Cartlark saves the edge cases: both platforms in one shape, minor-unit prices, variable products, pagination limits, rate limits with retries, robots.txt, and change detection with state kept between runs.

How much will a run cost? $0.0008 per product delivered, nothing else. A 1,000-product store is $0.80; a daily monitor on a 500-product store that changes 10 prices costs about $0.01 a day.

Can I get more than 250 products? Yes, set maxProductsPerStore up to 50,000.
