How WinWatcher finds a winner, without guessing. Four steps, mostly automatic.

  1. 01EXTENSION

    You visit a store

    The sidebar shows its numbers at once. Follow it in one click, or let auto-follow collect it.

  2. 02EVERY SCAN

    4,918 products saved in order

    Every scan saves the order

    Up to 5,000 products in Shopify's own best-selling order, with prices and launch dates.

  3. 03DASHBOARD

    #1,348 → #4 · score 100

    Climbers stand out

    A product that jumps hundreds of places in a few days gets a high Winner score, with the reasons.

  4. 04MARKET CHECK

    NL GO · AU EARLY · US SKIP

    You check your market

    Market check tells you if someone already scales it where you sell: GO, EARLY or SKIP.

We watch the stores, not the Ad Library.

When a store starts scaling a product, it climbs their best-seller list. You hear about it before it lands in every “top 10 winners” list.

New · Visual History

See every change on their store.

Two ways to use it, one account.

Everything syncs by itself between the two: follow a store in your browser and it is in your online dashboard a moment later.

In your browser: the Chrome extension

Works on your own computer (Chrome, Edge, Brave). Open any Shopify store and see its numbers in a sidebar, follow it in one click, look up Meta ads, visits and reviews from your own browser, and let auto-follow collect competitors while you browse.

  • Bestseller position of the product you look at
  • Works on its own, also without the online dashboard
  • Auto-follow with a notice on the page

Anywhere: the dashboard on getwinwatcher.com

The same dashboard online, on any computer: stores, products, risers, market check and vendor spy. Start a scan there and your extension runs it; data other customers already measured shows at once.

  • Discord alerts, also when you are not looking
  • Import stores from Excel or CSV
  • Your account, browsers and invoices in one place

Made for people who test products.
