Free Shopify theme detector
Enter any Shopify store to see its theme, the original theme it is based on when it has been renamed, and the marketing tools it loads, with a mobile speed score from Google.

One page, six areas, about ten seconds. Every finding is a fact read from the site itself, explained in plain English.
WordPress, Shopify, Wix, Squarespace, Webflow, Drupal and more, with the version when the site shows it.
The theme or template, plus builders like Elementor or Divi and the plugins visible in the page.
Cloudflare, WP Engine, Kinsta, Vercel and others, plus analytics, ads, chat and payment tools.
Title, description, headings, structured data, sitemap and whether Google may list the page.
Image descriptions, page language and overlay widgets that do not make a site compliant.
Google PageSpeed for phones, with how long the main content takes to show.
You can check by hand too. These are the same signs the checker looks for.
Images and scripts load from cdn.shopify.com.
The page code contains Shopify.theme with the theme name inside.
Adding /admin to the address goes to a Shopify login.
Checkout pages run on checkout.shopify.com or show Shopify branding.
Free website audit
The checker reads one page. In a free audit I go through your whole site and tell you, in plain English, what is costing you customers and what to fix first. No cost, no obligation, and you keep the plan whoever does the work.
Book my free auditEvery installed app can add scripts to every page, and uninstalled apps often leave code behind. That is the most common reason a Shopify store is slow on phones.
Heavily edited themes can’t take theme updates without losing changes, so stores fall behind on new Shopify features.
Stores often rename their theme. Shopify still records the original theme it came from, so the checker shows both.
If it is based on a Theme Store theme, yes, from the Shopify Theme Store. Custom themes are built for one store and are not for sale.
Only the ones that load visible scripts, like reviews, email popups or chat. Back-office apps can’t be seen from outside.
Each one runs the same check, with notes for that platform. Thinking about a new site? Try the website cost calculator.
