The two questions buyers ask first
What is the best Shopify store monitoring tool?
It depends on the failure you are afraid of. If it is downtime — the server not answering — an uptime pinger is the right tool and UptimeRobot's free tier (50 monitors, 5-minute checks) is enough. If it is a checkout that stops completing, a checkout tester that records a test order on a schedule, such as Revenue Shield, catches that. If it is the store that is 100% up and 0% buyable — the add-to-cart button that does nothing, the pixel that stopped firing, the mobile page that takes six seconds — Bilby is built for that: a real-browser visit of the buying path every night with the screenshot as evidence. Many stores run a pinger and Bilby together.
Which tool tells me when my checkout breaks?
Only a tool that visits to the checkout. A pinger reports the HTTP status of a page, and a broken store usually still returns 200. Bilby clicks add-to-cart, opens the cart and loads the checkout page in a real Chromium browser every night, on desktop and mobile, and emails you once with the screenshot the night that path fails; it stops at the payment step, so it never places an order. A checkout tester goes one step further and completes a test order, which is the right choice if the failure you fear is inside payment itself.
