Know when your Shopify store stops letting people buy
A theme update, an app change, or a sold-out variant can quietly break the buy path while the store still loads fine. A reverted price, a hidden add-to-cart, a dropped pixel. CopyMosaic checks your live storefront every day and emails you the day a customer can't buy.
Monitoring is $9/mo for founders, locked forever — up to 5 money pages, billed monthly, cancel anytime.
On Shopify, the things most likely to break are the things you didn't touch: an app auto-updates, a theme change reverts a tweak, a variant goes out of stock and hides the only buy button on the page. The store stays up, the homepage looks fine, and a specific product page quietly stops selling. CopyMosaic loads your storefront the way a shopper does, checks what actually breaks on a Shopify store, and tells you the day one of them moves.
What quietly breaks on your Shopify store
A theme update reverts your price or copy
A theme republish or app update rolls a product back to an old price or drops a custom line you'd added. The page looks polished; the number is just wrong, and every shopper sees it.
Add-to-cart hides or breaks
A sold-out variant, a broken theme block, or an app conflict removes or disables the add-to-cart button. The product still shows; the one action that makes money is gone.
An app embed breaks the buy path
An upsell, reviews, or subscription app errors and takes part of the product or cart page down with it. The store's still 'up' - the path to checkout just isn't.
The Meta or Google pixel drops
A theme or tag change removes your tracking, so conversions stop reporting and retargeting audiences shrink. You optimize blind while spend keeps flowing.
Currency or market shows the wrong price
A markets or currency-app misconfiguration shows shoppers a price in the wrong currency or a broken converted amount. It quietly tanks conversion for a whole region.
How it works
Paste a storefront or product URL. CopyMosaic loads it like a shopper, runs about 30 checks on what they'd actually see, and shows you the result in seconds - free, no signup. Turn on monitoring and it re-checks the page every day and emails you the day something changes - including the app and theme updates you didn't make.

Questions
Does it complete a test order through Shopify checkout?
No. It checks the storefront a shopper sees from the outside: that the price is right, the add-to-cart is present and live, the buy path doesn't dead-end. Shopify's hosted checkout is their domain, so it can't place a real order - but it catches the breaks that stop one from starting.
Will it catch an app or theme update that broke something?
That's the main thing it's for. App and theme updates ship without asking you and are the most common silent break on Shopify. CopyMosaic re-checks daily, so a change that reverts a price or hides a button surfaces the next day, not next month.
How often does it check?
Free scans run on demand whenever you paste a URL. Paid monitoring re-checks your store - and up to five pages total - every day, and emails you the day something changes.
