Real User Experience Monitoring for Shopify

Your best-selling collection page might be a broken shelf right now.

Q: Will you place test orders or leave carts behind?

No. We browse collections, product pages and the cart, and we stop there. We never submit an order, and we never create a checkout.

Q: Will this skew my Shopify analytics or conversion rate?

Our bot uses a published, declared user agent, so you can exclude it in one filter. We never disguise our traffic as a human shopper.

Q: Will monitoring slow my store down?

Not the way an app would. We add nothing to your theme, because we visit from the outside exactly like a shopper does.

Q: Does this affect my Shopify online store speed score?

No. That score is generated by Shopify from its own Lighthouse runs. RUX is separate, and it measures what your speed score can’t: real devices, real networks, real countries.

Missing product images. Prices that never render. Filters that don’t respond. Cards stacked wrong on a mid-range Android. Your store is up, your theme preview looks fine, and the shopper who clicked your ad is looking at an empty shelf.

The problem

Your theme preview isn’t your storefront.

The theme editor renders on your laptop, on your connection, with your cache warm. Your shopper opens the same collection on a three-year-old Android, over mobile data, with eleven app scripts fighting for the main thread.

The store is up. The shelf is empty.Product images time out, and your best sellers render as grey boxes.

Priced at nothing.A currency or metafield app fails, and half your grid shows no price at all.

Nobody tested that breakpoint.The layout holds on your phone and collapses on the one your shoppers actually own.

1

Add your store URL.

No app install, no theme code, no snippet. We map your key templates: home, collections, product pages and cart.

2

We shop it like a customer would.

A full browser session on a real device profile, at real viewport breakpoints, over a residential connection in the countries you actually sell to.

3

We record the whole shelf.

Every frame of the render, per-block load timing, Core Web Vitals, and which script held up your product grid.

4

We tell you when it changes.

Baselines are learned per page, so publishing a theme or installing an app doesn’t quietly cost you a week of sales.

Cloud-to-cloud routes are the fastest path on the internet, and none of your shoppers use them. We check from consumer ISP connections in the countries you sell to, so the numbers match what your customers feel.

Mid-range Android, flagship iPhone, tablet, laptop, wide desktop. Most Shopify traffic is mobile, and most shelf bugs live at a breakpoint nobody opened.

Monitoring that installs an app makes the store it measures slower. We add zero weight, zero scripts and zero theme changes, because we visit from the outside like a shopper.
