App Telemetry

Front-end app scanner for your Shopify storefront

Know Exactly What's Running on Your Storefront (and What It's Costing You)

Shopify merchants install apps to grow their business. Reviews, upsells, analytics, chat widgets, loyalty programs. But every app injects JavaScript into your storefront, and over time that stack compounds. Pages slow down. Core Web Vitals drop. Conversion rates suffer. And when something breaks, it's nearly impossible to figure out which app caused it.

App Telemetry scans your storefront the way a real customer experiences it. Using an actual Chrome browser, it visits your homepage, collection page, and product page. It detects every script running on your site, matches them against 300+ known Shopify app signatures, measures their performance impact, and flags conflicts. Unknown scripts get classified by AI so nothing slips through.

Instead of guessing which apps are the problem, you get a health score from 0 to 100, per-app impact ratings, conflict detection, and specific recommendations. You'll know exactly what to keep, what to fix, and what to remove.

Already Uninstalled Apps but Still Seeing Slowdowns?

Shopify apps often leave behind JavaScript, tracking pixels, and injected code even after you uninstall them. App Telemetry detects this leftover code and tells you exactly what's still running, so you can clean up what other tools miss.
