# App, theme, and pixel detection

> How StoreInspect detects visible storefront technology.

StoreInspect detects public storefront signals for Shopify apps, themes, pixels, analytics tags, and marketing tools.

## Visible signals

Detection checks signals such as:

* Script URLs and known app domains.
* CSS assets and theme file paths.
* Theme names and structure clues.
* Tracking-pixel scripts and initialization patterns.
* DOM elements and storefront metadata.

## When detection is positive

A detected app, theme, or pixel means the signal appeared on the storefront when StoreInspect analyzed it.

## Missing detections

A missing detection is not always proof that a store does not use a tool. Some tools are backend-only, private, custom implemented, or hidden behind consent and regional loading behavior.

## How to use detection in prospecting

* Has App and Has Pixel filters find technology users.
* Excludes App and Excludes Pixel filters find possible gaps.
* Combine technology filters with traffic, revenue, Shopify Plus, category, and contact role filters.
* Review high-value accounts manually before making specific outreach claims.

<Info>
  API and MCP integrations return the same StoreInspect technology data shown in the web app. They do not scan brand-new domains during every request.
