Shipping rates
Test carts confirm shipping options appear for each address you sell to, including live carrier rates.
Checkout Canary · Shopify app
Checkout Canary tests your checkout around the clock. It confirms shipping options appear, checks that your discount codes still apply, and emails you once when something breaks and once when it is fixed.
No orders are placed and no customer data is touched.

Why it exists
A Shopify update, a new app or a settings change can remove your shipping rates or break a discount code, and nothing tells you. Shoppers just leave. Checkout Canary builds real test carts on a schedule, so you find out in minutes instead of days.
