Does "Add to Cart" actually work on your store?
A broken add-to-cart button or a checkout page that fails to load is the single most expensive bug a store can have — and it's exactly the kind of thing merchants rarely test themselves, because your own cart is usually cached or logged in differently than a first-time visitor's.

The exact first two steps of a real purchase
This is the only scan on the site that briefly interacts with your live cart. It adds one test item using Shopify's public Ajax cart API, confirms the cart updated correctly, confirms checkout loads, then removes the test item — every time.
Add-to-cart mechanics
We POST to your storefront's public cart API for a real product and variant — the same request your theme's Add to Cart button sends — and confirm it succeeds.
Cart math
After adding the item, we read the cart back and confirm the item count and total price actually reflect what was just added.
Checkout page load
We load your checkout URL to confirm it opens without erroring. This is a page load only — nothing is ever filled in or submitted.
Clean teardown
The test item is always removed from the cart afterward, whether the test passed or failed. Nothing is left behind.
You test your store logged in. Shoppers never do.
This check simulates the exact first two steps of a real purchase, the same way a brand-new visitor experiences them: click add to cart, land on checkout. It catches regressions from a recent app install, theme update, or checkout customization — the kind of thing a merchant testing with their own logged-in, cached browser session usually never notices, because their cart already "works" for them.
A store can look perfectly fine on every page and still have a broken purchase path. This is the check that catches it before a customer does.
What confirming your purchase path does
Catch a broken purchase path early
A failed add-to-cart or checkout costs real sales, every hour it goes unnoticed. Finding it before customers do is the whole point.
Tests what a first-time visitor sees
Not a cached, logged-in session — the exact flow a brand-new shopper on a brand-new device experiences.
A self-cleaning test
Nothing lingers in your store's cart data. The test item is removed immediately, every single time.
Peace of mind after changes
Just shipped a theme update or installed a new app that touches cart or checkout? Confirm nothing broke in seconds.
Exactly what happens, step by step
Because this check touches your live cart, we want to be precise about every step — no vague summaries.
1. Find a sample product
We find one sample product from your public catalog to use as the test item.
2. Add it to a temporary cart
We add one unit of that product to a temporary cart using Shopify's own public Add-to-Cart API — the same request your theme's Add to Cart button sends.
3. Confirm the cart updated
We read the cart back and confirm the item count and total price are correct after the add.
4. Load checkout — nothing more
We load your checkout page URL to confirm it opens without an error. We never type into or submit any field there.
5. Clear the test item
We immediately clear the test item from the cart, every time, whether the test passed or failed.
Common questions
Does this place a real order or charge anything?
No, absolutely not. It only adds an item to a cart and loads the checkout page to confirm it opens. It never enters or submits payment, shipping, or contact information, and no order is ever created.
Will this affect my inventory or leave a cart in my store's data?
The test cart is cleared immediately after the check completes, or immediately if anything fails — the same as any visitor abandoning a cart, which happens constantly on every live store. Nothing persists.
Could this trigger abandoned-cart marketing emails to a real customer?
No. This uses a disposable scanner session with no email or customer account attached, so it cannot match to any real customer or trigger abandoned-cart flows tied to an email address.
Why do you need to add a real item instead of just checking the page HTML?
Broken add-to-cart and checkout bugs are usually only visible when you actually trigger the request-and-response cycle. Reading static HTML alone, like the other 18 scans on this site, can't catch a cart API that returns an error or a checkout page that fails to load.
