Shopify Detector — Frequently Asked Questions

Our detector fetches the public HTML, CSS, and JavaScript of the URL you provide, then uses fingerprinting rules to identify the theme and any installed extensions. Most detections complete in under 2 seconds.

RevealTheme's Shopify theme detector identifies the active theme on any Shopify storefront in under two seconds. Paste any Shopify store URL to instantly see the theme name, theme version, store ID, theme ID, and the store's render region. The detector uses Shopify's own JavaScript globals — the same data Shopify itself exposes to make sites work — so detection accuracy is essentially 100% on any live Shopify store. Works on both Shopify-hosted myshopify.com domains and stores on custom domains.

How to use the shopify theme detector

  1. Paste any Shopify store URL above. It works on both *.myshopify.com URLs and custom domains.
  2. Click 'Detect Theme'. We fetch the homepage of the store using a standard browser User-Agent.
  3. The detector scans the HTML for the BOOMR JavaScript object that every Shopify store ships with — this contains the theme name, theme version, and store metadata.
  4. We also check Shopify.theme and Shopify.shop JavaScript globals as a fallback.
  5. Results are displayed within two seconds — theme name, version, theme ID, store ID, and render region (Shopify CDN location).

What is a Shopify theme detector?

Shopify is a hosted eCommerce platform that powers over 4 million online stores worldwide. Each store runs a 'theme' that controls the visual design, product page layout, cart behavior, and checkout flow. Shopify theme detection differs from WordPress theme detection because Shopify themes don't expose file paths in the HTML the way WordPress themes do. Instead, every Shopify store embeds a JavaScript object called 'BOOMR' (Boomerang, Shopify's RUM performance library) which contains the theme name, version, and store ID. RevealTheme's Shopify detector parses this object. Because BOOMR is required for Shopify's own analytics, it's present on every live Shopify store — making detection effectively universal. The detector also identifies the Shopify CDN region serving the store, which can help diagnose performance issues.

Common use cases

  • eCommerce designers researching themes that converted well for similar stores
  • Agencies auditing a client's existing Shopify store before a redesign quote
  • Merchants comparing their theme against competitors in the same vertical
  • Theme buyers wanting to verify a theme is in active use before purchasing
  • Developers checking the theme version to understand which Liquid features are available
  • Shopify theme developers tracking adoption of their own themes

Frequently asked questions

Does the Shopify detector work on custom domain stores?

Yes. Whether the store is on store.myshopify.com or its own custom domain like brand.com, the BOOMR JavaScript object is identical, so detection works on both.

Why does the detector show 'Shopify detected, no theme name'?

A small percentage of Shopify stores use custom themes built by agencies that don't include a theme name in the BOOMR data. In those cases we confirm the site is on Shopify but can't extract a specific theme name.

Can it tell me if the theme is a free or paid theme?

Indirectly. If the detected theme name matches a name from the Shopify Theme Store (Dawn, Sense, Refresh, Crave, Studio, Origin, Ride, Colorblock, Craft, Spotlight, Publisher, Trade, Local), it's a free Shopify theme. Any other name is typically a paid third-party theme or custom theme.

Does it work on Shopify Plus stores?

Yes. Shopify Plus uses the same theme architecture as standard Shopify, so detection works identically.

Is the theme name accurate?

The theme name is what the store owner set in their Shopify admin — sometimes that's the original theme name (e.g., 'Dawn'), sometimes it's a custom name they chose (e.g., 'Holiday 2025 v2'). We show whatever the store owner saved.
