About ThemeScope

The story behind the tool and who's building it.

ThemeScope started with a question every store owner eventually asks while browsing a shop they admire: what theme is this built on? The answer used to mean digging through page source or installing a browser extension. We wanted a version anyone could use in five seconds, from a phone, with nothing to install.

So ThemeScope does one thing well: you paste a Shopify store's address, and it reads the store's public source to tell you the theme it runs, whether that theme comes from the official Shopify Theme Store or was custom-built, and — when the store happens to expose it — a version number. If the site isn't on Shopify at all, it says so plainly instead of guessing.

Why we built it

Choosing a theme is one of the highest-leverage decisions a new store makes. It shapes how fast pages load, how products are presented, and how easily a shopper reaches checkout. Being able to see what themes successful stores in your niche actually use turns that decision from a guess into research. ThemeScope is meant to make that research trivial.

What we believe about honesty

A lot of detector tools show a confident answer even when they're unsure. We'd rather be accurate than impressive. When a store runs a heavily customised or headless theme, the public theme name simply isn't there — so we report "custom" rather than inventing a name. And because Shopify's public theme data doesn't include a version number, we only show a version when a specific store leaks one in its own code. No fabricated numbers.

How it stays free

The detector is free to use as often as you like. We cover running costs with unobtrusive display advertising and, over time, guides that help store owners make better design decisions. We don't sell your data, and we don't store the URLs you check.
