What we check

36 ways a checkout breaks. We look for every one.

Every hour a real browser walks your store like a shopper — product, cart, checkout, payment — and places a real order. These are the failures it can name, each with the step where it happened and a screenshot.

Store 4 checks

  • The store does not answer or times out
  • A maintenance page is up
  • The site is not the platform it should be (a parked domain, a redirect)
  • Customer login fails for B2B stores

Product 4 checks

  • The product page is gone
  • The product cannot be bought: no price, out of stock, options that never enable the button
  • Prices hidden behind a login
  • The product page throws an error

Cart 5 checks

  • Add to cart does nothing
