Running a Shopify store means constantly checking what competitors are doing and confirming your own tracking is set up correctly. These extensions let you inspect any Shopify storefront's theme and apps, research product and store data, and verify Meta Pixel events fire as expected, all from the toolbar.

Inspecting a competitor's Shopify store

Koala Inspector shows the theme, installed apps and bestselling products of any Shopify store you visit, which helps you benchmark design choices and see which apps competitors rely on. PPSpy adds store and product research aimed at dropshippers, surfacing store traffic estimates and product performance signals from the same storefronts.

Checking the tech behind any storefront

Wappalyzer detects the theme, apps, analytics tools and page builders behind any website, including non-Shopify competitors selling similar products. It's a quick way to confirm whether a rival site is even built on Shopify, or to spot a review app or upsell tool worth evaluating for your own store.

Verifying your own store's tracking

Meta Pixel Helper checks that your Meta Pixel fires the right events, such as PageView and Purchase, on your own storefront. Running it after any theme or app change catches broken tracking before it affects ad reporting, which matters more the more you spend on Meta ads.

Best Chrome extensions for Shopify merchants: FAQs

What are the best Chrome extensions for Shopify merchants?

Koala Inspector, PPSpy, Wappalyzer and Meta Pixel Helper cover the most common Shopify merchant tasks: inspecting competitor stores, researching products, detecting a store's tech stack and verifying your own pixel tracking.

How can I see what theme a Shopify store is using?

Install Koala Inspector or Wappalyzer, then visit the store and click the extension's toolbar icon. Both detect the Shopify theme in use directly from the page's code, without needing store access.

Is there a Chrome extension to inspect Shopify apps a store uses?

Koala Inspector lists the apps a Shopify store has installed alongside its theme and bestselling products, which helps you see which apps competitors rely on for reviews, upsells or page building.

What is a Shopify inspector extension?

A Shopify inspector extension reads the public code of a storefront to report its theme, installed apps and sometimes bestsellers or estimated traffic, all without needing admin access to that store.

How do I check if my Meta Pixel is working on Shopify?

Install Meta Pixel Helper, visit your storefront, and its toolbar icon turns green when it detects the pixel and lists the events firing, such as PageView, AddToCart and Purchase.

Are Shopify spy extensions like PPSpy legal to use?

Yes. These extensions read publicly available information from storefronts you visit, similar to viewing a page's source code. They don't access private admin data or bypass any store's security.

Can I tell if a website is built on Shopify without an extension?

You can check the page source for Shopify-specific script tags and CDN URLs, but Wappalyzer or Koala Inspector does this automatically and also names the theme, which is faster for regular research.

Do Shopify research extensions slow down browsing?

No. Extensions like Wappalyzer and Koala Inspector only run their detection when you click the toolbar icon or open a new page, so they don't add noticeable load time to normal browsing.

What is the best free Chrome extension for Shopify competitor research?

Koala Inspector's free tier covers theme, app and bestseller detection for any Shopify store, which is enough for casual competitor checks before you'd need a paid research tool.

How do dropshippers use Chrome extensions for Shopify?

Dropshippers commonly use PPSpy to research which products and stores are performing well, then Koala Inspector or Wappalyzer to see the theme and apps behind those same stores before building their own.

Do these extensions work on Shopify Plus stores?

Yes. Theme and app detection extensions read the same public storefront code regardless of Shopify plan, so they work the same way on standard Shopify and Shopify Plus stores.
