For an existing store: paste your URL and we detect the theme automatically. For a new store: answer five questions and we score 20+ free and premium themes to find your best five. No signup, results in seconds.
It loads the store's public pages and reads the theme name, version and where it came from out of the markup Shopify itself publishes. Nothing private is accessed and the store owner is not notified.
It reports the base theme a store started from. Heavy customisation can obscure the name, in which case you get the closest match rather than a guess presented as certainty.
Only on live Shopify stores. Password-protected stores, headless storefronts and stores on other platforms return no result.
For most stores Dawn is enough — it is Shopify's reference implementation of Online Store 2.0. A paid theme earns its cost when it ships a specific layout or feature you would otherwise pay a developer to build.
Yes, with no sign-up and no limit. We built it because we use it ourselves before quoting on a store.
View the page source and search for Shopify.theme, or type Shopify.theme into the browser console. The schema_name field is the theme's real name even when the merchant has renamed their copy.
The name field is the merchant's own label for their copy. The detector prefers schema_name, which comes from the theme itself, so a store calling its theme "Summer sale" still shows the theme it is built on.
If theme_store_id is null and schema_name is not a theme you can find in the Theme Store, the theme was uploaded — bought elsewhere, built by an agency, or heavily forked.
If it is a Theme Store theme, yes — install it from the Theme Store, free or for a one-off price. Another store's custom code, images and text are not part of the theme and are not yours to copy.
The detector does this for you, but the method is simple and worth knowing — it reads the same data you can see yourself.
Open the store, view the page source (Ctrl+U on Windows, Cmd+Option+U on a Mac) and search for Shopify.theme. Every Shopify storefront prints a small object there with the theme's name, ID, version and role.
Prefer the console? Open developer tools, go to Console, type Shopify.theme and press Enter. You get the same object without scrolling through markup.
The fields do not carry equal weight. The merchant can rename their copy of a theme to anything, so the most visible field is the least reliable one.
A null theme_store_id with an unfamiliar schema_name usually means a theme bought outside the Theme Store, a theme an agency built from scratch, or a Theme Store theme forked so heavily it was renamed. Asset file names help: base.css and global.js are typical of Dawn and the themes derived from it.
Many stores run one of Shopify's own free themes. Dawn has been the reference Online Store 2.0 theme since 2021; Horizon, released in 2025, is Shopify's newer theme family built around theme blocks. If schema_name shows one of these, what you like about the store is configuration, content and photography — not a purchase.
Two stores on the same theme can look and perform completely differently because of sections, apps and content. If you are studying a competitor, check their apps too, and look at how their product pages are structured — that usually matters more than the theme.
