How does this differ from the App Detector?

The App Detector finds installed apps by scanning for script tags and footprints. This detector specifically looks for theme app extensions—the modern integration method where apps embed blocks into the theme itself.

What are theme app extensions?

Theme app extensions are the modern way apps integrate with Shopify themes. They use theme blocks and app embeds instead of injecting scripts directly, making apps safer and more maintainable.

Why do some extensions show no name?

Our catalog doesn’t have every theme extension mapped yet. Unnamed extensions are detected by their handle (like "my-app-block") but we couldn’t match them to an app name in our database.

Why are there no app icons or ratings?

Theme extensions are identified by their handle, not by an App Store listing. In this first version, we show the extension name and handle without icons or ratings, as that data isn’t available for theme extensions in the same way it is for apps.

Do I need to install a Chrome extension?

No. It runs as a web tool, so there’s nothing to install and nothing tracking your own browsing. Paste a URL and get the result in the same tab.

What is a theme app extension detector?

A theme app extension detector analyzes a live Shopify store and identifies the theme app extensions embedded in it—these are the modern way apps integrate with themes via blocks and app embeds.

Unlike traditional app detectors that scan for script tags and footprints, our detector specifically looks for theme extension handles embedded in the theme blocks. This gives you visibility into the modern app integration layer that many tools use now.

Paste a URL and get your answer straight away: no Chrome extension to install, no account, no limit on how many stores you check.

Why it matters

Seeing a store’s theme app extensions reveals how apps are actually integrated at the theme level, not just what’s installed. This affects theme performance, customization flexibility, and migration complexity.

Theme extensions are the future of app integration—they’re safer, more maintainable, and theme-aware. Knowing which stores use them helps you understand their app maturity and technical stack.
