Monitor

Shopify monitor for the plugin-update day that quietly broke the cart.

Shopify stores rarely go hard-down. They get slow on the cart page after a payment-plugin update, or the storefront times out the morning a Facebook ad starts spending. SiteGuardian watches the URLs a shopper types, on a minute cadence, before the spend turns into a refund queue.

  • Watches your Shopify storefront, /cart, /checkout, and admin login as separate URLs.
  • Tight slow threshold on /checkout. 1.5 seconds is sane for most stores.
  • Probes every minute on Pro. Fast enough to catch the day a payment-plugin update pushes load above threshold.
  • SSL expiry alerts on every plan. Shopify-managed certs are not really managed.
  • No Shopify app install, no theme edit, no theme-app-extension hookup.

How it works

Setup, in three beats.

  1. Step 01

    Add the URL a paying shopper types first

    Paste your storefront root, /cart, /checkout, and the admin login. Set a tight slow threshold on /checkout (1.5 seconds is sane) and a slightly looser one on /cart. SiteGuardian starts probing inside the next minute.

  2. Step 02

    Let the alerts catch the plugin-update day

    Most Shopify checkout slowdowns come from a payment-plugin update or a tracking-pixel script balloon. The minute cadence catches the day the change happens, before the cart-timed-out metric in Shopify Analytics tells you a week later.

  3. Step 03

    Catch the storefront timeout before the spend turns into refunds

    A storefront that returns 500 on a Facebook-ad push morning loses the spend. SiteGuardian probes every minute on Pro, so the email reaches your inbox the second the page stops — before the next would-be buyer arrives at a timeout.

What the alert actually says
