Frequently asked questions
Is this really free?
Yes. Anonymous users can run 1 free scan per day. Create a free account to get 5 scans/day. The free tier covers on-demand scanning only — continuous monitoring is a paid feature.
What does the checkout tester actually do?
We launch a real browser (Chromium), navigate to your store, find an in-stock product, add it to cart, proceed to checkout, and validate that the payment form renders correctly — exactly what a real customer does.
Why should I test after a theme update specifically?
Theme updates are the #1 cause of Shopify checkout failures. New theme versions can introduce JS conflicts with installed apps, break cart AJAX calls, or lose custom checkout.liquid edits. Visual checks miss these — only a full checkout simulation catches them.
Do I need to install anything?
No. It's entirely web-based. Just enter your store URL and we handle the rest.
Will this affect my store or create real orders?
No. We never complete a purchase or enter real payment details. The test stops at the checkout page after verifying it loads and renders correctly.
What if my store is password protected?
The test will fail to access your store. Temporarily remove the password protection to run the test, then re-enable it.
Can I monitor automatically instead of testing manually?
Yes. Pro monitoring runs a full checkout test every 30 minutes and alerts you instantly if something fails. It's from $29/month for one store.
Skip the manual check — monitor automatically
TestPilot can run this test every 30 minutes and email you the moment something breaks. From $29/month.
