Detect Shopify Apps and Plugins on Any Competitor Store

Every Shopify store runs on apps. Reviews, loyalty programs,
upsell flows, live chat, email capture, subscriptions — the Shopify
App Store has over 8,000 apps covering virtually every function.

When a competitor's store converts well, part of the reason is
usually their app stack. Knowing what they're running is competitive
intelligence that's sitting in their frontend code, publicly
accessible if you know where to look.

What's Detectable

Most Shopify apps load JavaScript, CSS, or external scripts that
leave identifiable fingerprints in the page source. Common
categories that are usually detectable:

Reviews and social proof: Yotpo, Okendo, Judge.me, Stamped.io —
all leave distinctive script tags and CSS classes.

Loyalty and rewards: LoyaltyLion, Smile.io, Yotpo Loyalty show up
through their widget scripts and initialization code.

Upsell and cross-sell: ReConvert, Bold Upsell, Zipify Pages
appear via their page injection scripts.

Live chat: Gorgias, Tidio, Zendesk, Intercom, Klaviyo chat —
each has a recognizable loader script.

Email capture and popups: Klaviyo, Privy, Justuno have distinct
script signatures.

Shipping and fulfillment: Some fulfillment apps add tracking
widgets that are detectable in the order status pages.

How to Do This Manually

• Open DevTools (F12) on any Shopify store page, go to the Network
• tab, and look at script and stylesheet requests. You'll see external
• domain requests that often include the app name:
• cdn.yotpo.com (Yotpo)
• static.klaviyo.com (Klaviyo)
• cdn.loyaltylion.net (LoyaltyLion)

Alternatively, View Page Source (Ctrl+U) and search for common
app domain names.

Faster Method: Shopify Theme Detector

• Shopify Theme Detector is a Chrome extension that automates app
• detection alongside theme identification. Click the extension button
• on any Shopify store and it shows:
• The active theme name
• A list of detected apps and technologies
• Shopify plan indicators where detectable

Instead of manually parsing network requests and source code, you
get a summary in under a second.

How to Install and Use It

1. Install from the Chrome Web Store
2. Visit any Shopify store you want to analyze
3. Click the extension button
4. Review the app list in the popup

For deeper research, cross-reference detected app names with their
Shopify App Store listings to understand pricing, features, and
alternatives.

What to Do With This Information

Don't copy blindly. A competitor's app stack reflects their specific
business model, customer base, and conversion strategy. What works
for them may not map to your store.

• Instead, use it to:
• Identify gaps in your own stack (they have a review app, you don't)
• Evaluate apps you're considering (see them running in a real store)
• Understand what successful stores in your niche prioritize

App Cost Considerations

Many of the apps detectable on high-performing stores are not cheap.
Yotpo, Okendo, and similar enterprise review platforms can run
$200-600/month. LoyaltyLion and Smile.io have significant monthly
costs at scale. Understanding what a competitor is spending on
their app stack helps calibrate what investment might be needed
to compete at that level.

Limitations

Server-side apps leave no frontend traces. Apps that run purely
through Shopify's backend (some fulfillment apps, certain custom
checkout tools on Shopify Plus) may not be detectable from
frontend analysis.

Also, stores can obfuscate their stack by using custom script
loaders or proxying external resources through their own domain.
Large, sophisticated stores sometimes do this.

Conclusion

Your competitors' app stacks are largely visible if you know how
to look. Surfacing that information quickly — without manual
source code parsing — lets you do competitive research at scale
and build a clearer picture of what's working in your market.
