CartSentry

CartSentry protects Shopify Plus and high-volume DTC brands from silent checkout failures and revenue loss.

Unlike traditional error-tracking scripts that inject heavy JavaScript into the store and slow down conversions, CartSentry runs 100% external synthetic tests using headless Chromium instances via Playwright every 15 minutes.

Key Highlights:

• Zero Code Injection: Zero theme slowdown and zero client-side tracking interference.
• End-to-End Synthetic Sweeps: Simulates product selection, drawer cart interactions, and checkout boundaries.
• Root-Cause Diagnostics: Catches Checkout UI Extension clashes, broken coupon inputs, and failing third-party scripts.
• Instant Alerts: Immediate Slack, Email, and Webhook dispatch with DOM stack traces, latency logs, and automated failure screenshots.
