Test setup
Paste a product URL. Sentinel finds add-to-cart and checkout controls before monitoring starts.
Checkout monitoring for Shopify stores
Know if customers can buy right now.
Checkout Sentinel runs a real browser from product page to checkout, confirms failures before alerting, and sends a clear incident brief when the purchase path breaks.
Real browser checks
Not just uptime pings.
Retry before alert
Designed to avoid noisy false alarms.
Merchant-readable incidents
Impact, likely cause, next actions, evidence.
How it works
From product page to checkout, with evidence.
Monitor the path
A browser loads the product, adds it to cart, and confirms checkout is reachable.
Alert with evidence
Confirmed failures produce an incident brief with screenshot, failed step, and next actions.
Incident reports
Alerts that tell the owner what to do next.
Each confirmed failure includes customer impact, likely cause, next actions, browser steps, console issues, and a screenshot when available.
