What is a Shopify app detector?
A Shopify app detector is a free tool that identifies which third-party apps a Shopify store has installed by fingerprinting its live storefront.
Enter a Shopify store domain into the SalesTracker app detector and it scans the store's HTML, JavaScript bundles, script URLs, and network requests for signals unique to each known Shopify app, loader scripts, embedded snippets, DOM markers, and CDN paths.
The result is a categorized list of installed apps grouped by function (marketing, reviews, analytics, upsells, pop-ups, subscriptions, translations, and more) with a confidence rating for each detection. You can see at a glance which categories the store invests in and which app it picked in each one.
Ecommerce operators, Shopify agencies, and competitive researchers use a Shopify app checker to reverse-engineer successful stores' tech stacks, understand which tools are actually used in production, and decide which apps to try themselves. It is a much stronger signal than App Store ratings because you are seeing the apps that real stores keep installed in production.
What this tool detects
Installed Apps
See a full list of third-party apps running on the Shopify store, everything from Klaviyo to Judge.me to Rebuy, categorized and ranked by detection confidence.
Categorized by Function
Apps are grouped into functional categories, marketing, reviews, analytics, upsells, subscriptions, pop-ups, and more, so you can see exactly where a Shopify store is investing in third-party tools.
Confidence Levels
Each detection comes with a high / medium / low confidence rating based on how strong the fingerprint signal is. You always know which apps are certain and which are likely.
Instant & Free
Cached Shopify stores return app lists in seconds. Fresh scans take 10-20 seconds for stores we haven't seen before. No signup, no credit card, no usage limit.
How it works
Enter a Shopify store
Paste any Shopify store URL or domain name. The app detector auto-confirms the store is on Shopify before running the scan.
We fingerprint the storefront
Our system fetches the store's HTML, JavaScript bundles, inline scripts, and network requests, then matches them against a database of known Shopify app signatures.
See every detected app
Within seconds you see every detected Shopify app, grouped by category, each with a confidence level and a direct link to the app's Shopify App Store listing.
When to use a Shopify app checker
Reverse-engineering competitor tech stacks
When you are studying a top Shopify store in your niche, the app detector shows exactly which apps they use for reviews, email, upsells, and analytics. It turns 'I wonder what they use for X' into a definitive answer in seconds.
Finding the best apps in any category
Before committing to a Shopify app, run a handful of successful stores in your niche through the detector. The apps that show up repeatedly are the ones production stores actually keep installed, a much stronger signal than App Store ratings.
Pre-sales discovery for Shopify agencies
Agencies use the app detector to audit prospect stores before a pitch. Knowing which apps a prospect already runs, and which obvious gaps they have, lets you walk into the conversation with concrete recommendations rather than generic questions.
Competitive intelligence for app developers
Shopify app developers use the detector to study which stores run competing apps, which app combinations are common, and which gaps exist in their own category, all without manually poking around stores by hand.
Also known as
The SalesTracker Shopify app detector is the same tool you may have searched for as a Shopify app checker, Shopify plugin detector, Shopify tech stack checker, Shopify app lookup, Shopify store app finder, Shopify installed apps checker, or 'what apps does this Shopify store use'. However you phrase it, the workflow is the same: enter a Shopify store domain and see every installed app in seconds.
Frequently Asked Questions
We fetch the storefront's HTML, JavaScript bundles, and inline scripts, then match them against a database of known Shopify app fingerprints. Each known app has a distinctive combination of script URLs, DOM elements, and CDN paths, when we see a match, we report the app and a confidence level.
The fingerprint database covers the most popular Shopify apps across every major category, marketing (Klaviyo, Omnisend, Privy), reviews (Judge.me, Yotpo, Loox, Okendo), analytics (GA, Triple Whale), upsells (Rebuy, ReConvert, Bold), subscriptions (Recharge, Bold), translations, pop-ups, and many more.
Yes, that is exactly what this tool does. Enter the store's domain, wait a few seconds, and you see every detected app grouped by category. It is the fastest way to answer 'what apps does this Shopify store use' for any competitor.
High-confidence detections are essentially definitive, the fingerprint signals are unique to the specific app. Medium-confidence detections are very likely but depend on shared patterns. Low-confidence detections are flagged as hints rather than confirmations, so you always know how much to trust each row.
Cached results are instant. For stores we have not scanned before, or when you explicitly request a fresh re-scan, we need to fetch live HTML and JavaScript, which takes 10-20 seconds depending on the store's response time.
This app detector is Shopify-specific. It first confirms the site is a Shopify store, then runs the app scan. If the site isn't Shopify, it tells you that instead of returning irrelevant results.
Yes, with caveats. Custom apps and private Shopify apps that use standard Shopify webhook or script tag patterns often leave detectable traces. Fully private apps with no frontend footprint, for example backend-only integrations, do not show up in a frontend fingerprint scan, which is a limitation of any client-side app checker.
No. The Shopify app checker fetches public pages just like any browser. There is nothing that flags your scan as unusual, and merchants cannot tell a detection apart from a regular page load.
Manually reading page source works for big, obvious apps if you already know what their scripts look like. This Shopify plugin detector automates the full fingerprint match against hundreds of apps and returns a categorized list in one click, so you do not miss anything and do not have to memorize signatures.
Yes. Free users can see up to 5 detected apps per store. Pro subscribers unlock the full list with every detected app for every scanned store, which matters for stores that run 15 or more apps.
CSV export is a Pro feature. Free users can read the full UI list in-browser, while Pro subscribers can export detected-apps lists from every scanned store for bulk competitor research.
Combine it with the Shopify Traffic Checker to correlate app choices with actual traffic results, and the Shopify Theme Detector to understand the full tech stack. For example, if a high-traffic store runs a specific reviews app plus a specific email app, that combination is a strong signal worth testing yourself.
