How to See What Apps a Shopify Store Uses (Free Methods)

Method 1: The free Storefront Audit tool (fastest)

We built a free tool for exactly this: paste a store URL or its page source into the Storefront Audit tool and it lists the known apps it detects — Klaviyo, Yotpo, Bold, and many other app scripts.

It runs entirely in your browser. Nothing leaves your machine, no login, no signup.

What it sees: apps that load recognizable client-side scripts on the storefront. That covers most popular Shopify apps (email, reviews, popups, loyalty, bundles, payment providers).

What it doesn’t see: apps with no storefront script — back-office apps (inventory, bookkeeping), or apps that only touch the checkout API or admin. We’re honest about that limit.

Method 2: View source and search for script domains

If you want to do it by hand, open any store, right-click → View Page Source, and search (Ctrl+F) for these strings:

• cdn.shopify.com/extensions/ — this is where Shopify serves app scripts from. Every app script URL under this path includes the app name, e.g. klaviyo, yotpo, judge-me.
• cdn.shopify.com/s/files/ — theme and app assets.
• Known app CDNs: static.klaviyo.com, d1pnpjddp5v5qh.cloudfront.net (Yotpo), cdn.judge.me — search the app name and you’ll find its script host.

A quick copy-paste workflow: View Page Source → select all → copy → paste into our Storefront Audit tool, which does the matching for you and groups platform scripts separately from third-party apps.

Method 3: Browser network tab (live scan)

Open DevTools (F12) → Network tab → reload the store → filter by script. The request list shows every script the store loads, including app scripts. This catches scripts that only load after user interaction (scroll, click) — but you have to know which domain belongs to which app.

What about paid detection tools?

There are paid services that claim full app detection. Before paying, know the honest limit that applies to every method: apps that don’t load a client-side script are invisible from the outside. A paid tool can’t see what doesn’t load either. The free methods above cover the same ground for storefront-visible apps.

Checking your own store: the real audit

Seeing what apps a store runs from the outside is a starting point. The real audit — the one that saves money — happens from the inside:

1. Your app list vs. what actually loads. A store can have 20 apps installed and only 12 loading scripts. The other 8 are either unused or broken — and some are still billing you.
2. Duplicates. Stores run 4 email tools, or pay for a popup builder when their theme already includes one.
3. Unused subscriptions. The classic: installed “to try for a week” two years ago, still charging monthly.

The free tool tells you what loads on the storefront. For the full picture — your actual app list, API connection, and webhook health with read-only access — that’s what CostPilot Pro does (our tool, disclosed, 7-day free trial). The free methods in this guide work without it.
