How to Find a Shopify Store's Theme
How to find a Shopify store's theme with the SalesTracker Theme Detector: name the active theme, spot custom builds, and read the version.
The SalesTracker Theme Detector tells you which theme any Shopify store is running, whether it is an official Theme Store theme or a custom build, and the version when the store exposes it. The Theme Detector runs a live scan inside the Shopify Theme Detector tool, which needs a free SalesTracker account and uses one credit per lookup.
How to find a Shopify store's theme
You can detect a Shopify theme in two steps: paste the storefront domain and read the result. The scan reads only the store's public pages, so the merchant sees nothing different from a normal visit.
Paste the store domain and run the scan
Open the Shopify Theme Detector, paste the store's domain into the input, and click Detect. The live scan uses one credit from your free account. The tool reads the Shopify theme object, CDN patterns, and theme metadata to identify the active theme.

Read the detected theme
The result names the active theme and tags it as either an official Theme Store theme or a custom build. In the example above, the store returns a "Shopify Store" badge with the theme "Release - 06112026 - CN Web Team" tagged as a "Custom Theme," which tells you the merchant is running a bespoke build rather than a stock template.
One lookup, one credit
The Theme Detector runs a fresh live scan each time, so it costs one credit per lookup and needs a free SalesTracker account. There is no anonymous theme scan.
How to read the result
The Theme Detector answers three questions about a store's theme. Use the tags and labels in the result to interpret what the merchant has built.
Official theme vs custom build
A theme tagged as an official Theme Store theme means the merchant is running a stock template you can study or buy yourself. A "Custom Theme" tag means the store is on a bespoke build, so the design choices are unique to that merchant and not available as a downloadable template.
Theme version
When a store exposes its theme version, the result shows it. The version helps you tell whether a merchant is on a current release or an older one, which is useful when you are benchmarking design and feature freshness against competitors.
Headless storefronts
Some stores serve their storefront from a headless framework instead of a classic Liquid theme. The Theme Detector flags Hydrogen, Next.js, and Remix storefronts as headless, which signals a more custom, developer-led front end rather than a Theme Store template.
Frequently asked questions
How do I find what theme a Shopify store uses?
Paste the store's domain into the SalesTracker Theme Detector and click Detect. The live scan names the active theme and tags it as an official Theme Store theme or a custom build, using one credit per lookup.
Can the Theme Detector tell official themes from custom ones?
Yes. The Theme Detector tags each result as either an official Theme Store theme or a "Custom Theme." A custom tag means the merchant runs a bespoke build, not a stock template you can buy and install yourself.
Does detecting a Shopify theme require an account?
Yes. The Theme Detector runs a live scan that needs a free SalesTracker account and uses one credit per lookup. There is no anonymous theme scan, since every detection is a fresh read of the store's public pages.
What does it mean when a store is flagged as headless?
A headless flag means the storefront runs on a framework like Hydrogen, Next.js, or Remix instead of a classic Liquid theme. It points to a custom, developer-built front end rather than a Theme Store template.
