Shopify App Detector: Which Stores Use an App

Give it the Shopify apps you care about and a list of store domains. It tells you which stores use which app and shows the evidence. $1.50 per 1,000 domains.

Find public traces of Shopify apps on store homepages and export the results to CSV. Check a list of domains for known app signatures or provide your own patterns.

Quick start

1. Press Start. The form is already filled with this example input, so the first run returns real rows in under a minute:

{
  "apps": [
    "Klaviyo",
    "Judge.me",
    "Recharge"
  ],
  "customApps": [],
  "domains": [
    "allbirds.com",
    "colourpop.com",
    "gymshark.com"
  ]
}

2. Swap in your own values, or call the Actor through the Apify API, Make, Zapier, n8n or the Python/JS clients with the same JSON.
3. Download the results as JSON, CSV or Excel from the Output tab, or schedule the run to repeat.

Sample row (real run, trimmed)

{
  "domain": "colourpop.com",
  "isShopify": true,
  "usesAnyApp": true,
  "matchedApps": ["Klaviyo", "Swish wishlist", "Restock Rocket", "Wishlist King", "Okendo", "Gorgias (custom)"],
  "matches": [
    { "app": "Klaviyo", "via": "signature", "evidence": "Klaviyo" },
    { "app": "Swish wishlist", "via": "theme app extension", "evidence": "swish-wishlist-king" },
    { "app": "Restock Rocket", "via": "theme app extension", "evidence": "restockrocket-1" },
    { "app": "Gorgias (custom)", "via": "custom pattern", "evidence": "gorgias" }
  ],
  "notFound": ["Judge.me"],
  "themeName": "Colourpop/Main",
  "detectedApps": ["Yotpo", "Okendo", "Klaviyo", "Attentive", "Klevu", "Gorgias", "Klarna", "Shop Pay", "Triple Whale", "Elevar"]
}

How matching works

1. Built-in signatures for about 70 popular apps (Klaviyo, Judge.me, Yotpo, Recharge, Okendo, Gorgias and more).
2. Theme app extensions and app proxies: any other app name is matched against the app embeds and proxies the store loads.
3. Your own patterns: add a custom app with code snippets (e.g. a script domain) for exact control.

Who uses this

• App companies: find stores using a competitor's app, or check your own installs.
• Agencies and sales teams: filter a lead list to stores using (or missing) a tool.
• Analysts: measure app adoption in a set of stores.

How to use it

1. Add app names (one per line or comma-separated) and/or custom apps with patterns.
2. Add store domains. Turn on Only matching domains to keep just the hits.

Input fields

Field	Type	What it does
apps	array	App names to look for on each homepage.

FAQ

Can it miss an app? Yes, if the app loads nothing on the homepage (back-office apps). "Not found" means no public trace on the homepage, not proof that the store doesn't use it.

Do I need a Shopify API key to detect apps on store homepages? No vendor API key is required. The Actor checks each supplied domain's public homepage.

How do I choose apps and stores to check? Add app names to apps and store domains or URLs to domains.

Can I detect an app with my own homepage pattern? Yes. Add a name and one or more patterns to customApps. A match means the homepage HTML contains a supplied pattern.

Can I export app detection results to CSV or use MCP? You can download the dataset as CSV or connect an MCP client using this MCP tools URL.

How much does it cost to save 1,000 checked domains? On the Free/Bronze tier, 1,000 saved domain rows cost $1.50, plus the $0.00005 run start fee, for $1.50005. With onlyMatchingDomains enabled, filtered-out domains are free; unreachable domains are also free.
