Two-minute self-check
Your browser already knows. In two minutes you can see how many files one app adds to a page and how much they weigh, on your own store, with nothing to install and nothing to sign up for.
You'll need a laptop or desktop. The developer tools aren't on a phone. Chrome, Edge and Brave all work the same way.
Five steps
01
Open any page on your store. Press Cmd+Option+I on a Mac or F12 on Windows, then click Network in the panel that opens.
02
It's at the top of the panel. With it on, the browser downloads everything fresh, the way a first-time visitor would.
03
That hides the images and stylesheets and leaves the scripts, which are what slow a page down.
04
Into the filter box, in lower case, as the app is named in your Shopify admin. One word of the name is usually enough.
05
The two numbers are in the bar at the bottom: how many files that app loaded, and how much they weighed. That's one app, on one page.
A worked example
Measured the same way on my own Shopify site, with a review app's widget on the product page, then with the display I wrote in its place. The app still collects the reviews; the page no longer loads its widget.
On its own, not much yet. It's one app on one page. What it tells you is that the cost is real and you can see it, which is more than a bill ever shows.
From here there are two ways to go further. The calculator shows what all your apps cost in subscriptions. The Diagnostic Audit measures every one of them on your store, page by page, and tells you which ones earn their place.
The Diagnostic Audit measures every app your store loads. It starts with a free 30-minute call, where I confirm the price: $500, $1,000 or $1,500 depending on your store. The written report arrives within 7 business days.
