Short answer: Instant Data Scraper is a free Chrome extension by Flavr Technology. Its Chrome Web Store page (checked 22 Oct 2026; version 1.9.3, updated 16 October 2026) says it detects the data on a page with heuristic AI, follows “next” buttons and infinite scroll, lets you rename and filter columns, exports to XLS, XLSX or CSV, and keeps the scraped data in your browser. For one shop's listing page, once, it is probably all you need, and it costs nothing. Our Shopify & WooCommerce Product + Price Tracker runs in the cloud on Apify, reads each shop's structured product data (variants, SKUs, compare-at prices, stock) for several shops in one run, and can be scheduled. Free during launch; you pay only Apify platform usage.
The pain this page is about
“Before Black Friday on 27 November 2026 I want my three competitors' products and prices in a sheet.” A browser extension copies the table a page shows you; a catalogue export reads the product data behind the shop. Both can be the right answer.

Who should pick Instant Data Scraper instead
- You need one page or one shop, once, and the visible table (name, price, link) is enough.
- You want something free with no account on any platform, and you prefer the data to stay in your browser.
- The site is not Shopify or WooCommerce, or it is a marketplace.
Who our Actor fits better
- You want several competitors' whole catalogues, with variants, SKUs, compare-at (was) prices and stock, not just what one listing page shows.
- You want to re-run the same check before each sale or on a schedule, without clicking through pages.
- You prefer a tool that respects blocks: shops that refuse it are skipped and not charged.
No tool at all? A Shopify shop's public catalogue can be read in your browser at /products.json: see export a Shopify product list to CSV.
Try it on three shops first
Actor fee: free during launch · you pay only Apify platform usage
The Shopify & WooCommerce Product + Price Tracker is a pay-per-usage Actor on Apify: you pay only for the platform resources the run uses, with no extra developer charge (Apify docs). Apify's free plan is $0 and includes $5 of platform usage a month, no credit card (apify.com/pricing). Listing pages are free in the Actor's own design, and shops that are skipped or return nothing cost nothing. We do not quote a cost per 1,000 products; run a small test and read the usage in your Apify billing page. Built and published by Unadhi (disclosure).
Free gift: copy-paste input for a three-shop price check
Read the SHOPS_SUMMARY record after the run: it tells you which shops were skipped and why. No code at all? You can also read one Shopify shop's public catalogue in your browser at /products.json for free: see how to export a Shopify or WooCommerce product list to CSV and build a competitor price sheet.
Frequently asked questions
Is Instant Data Scraper free?
Yes. Its Chrome Web Store page (checked 22 Oct 2026) says the extension is completely free.
Does Instant Data Scraper send my data to a server?
Its store page says the scraped data does not leave your browser, and the developer's privacy declaration lists web history as data the extension handles. Read the developer's privacy policy for the details.
Can the Unadhi Actor scrape Amazon or other marketplaces like a browser extension can?
No. It refuses marketplaces by design and works only on independent Shopify, WooCommerce and schema.org shops.
Why use a paid-usage Actor when a free extension exists?
Only if you need several shops at once, variant-level data such as SKUs, compare-at prices and stock, or scheduled re-runs. For a one-off copy of one listing page, the free extension is the simpler choice.
What does the Unadhi Actor cost?
No Actor fee during launch. You pay Apify only for the platform usage of each run; Apify's free plan includes $5 of usage a month.
Not legal advice. Public product and price data is generally fine to read for your own comparison; respect each shop's terms and do not republish their content. Competitor prices and plans change; re-check their pricing pages before you decide. Spotted an error about any product on this page, including ours? Write to mininglife7@gmail.com and we correct it.
