PayGuard runs a real browser through your checkout every 30 minutes. If something fails — even at 3 AM — you get an instant email alert with error details. Free manual tests, always.
We'll email you the moment PayGuard launches — with an exclusive early-bird discount.
Free manual tests forever. Pro auto-monitoring with 3-day free trial. No credit card for free tier.
Checkout breaks silently.
An app update. A theme change. A Shopify outage. Most merchants find out from customers — or never find out at all.
Pro checks your checkout every 30 minutes — not just when you remember
Browser testing — we click buttons, not just ping URLs. HTTP 200 ≠ checkout working.
Setup required. Install, click "Test My Checkout", done.
Not just HTTP pings. We open a real browser: browse products → add to cart → checkout → payment page. Every step timed, every error captured.
Pro checks your checkout every 30 minutes, 24/7. You focus on your business — we'll tell you when something breaks.
Checkout fails → you get an email within seconds. Error details, affected step, and screenshot included. No more "my checkout was broken for 3 days."
Every minute your checkout is broken costs real money. Auto-monitoring catches issues before they impact revenue.
You're always tweaking themes, updating apps, and A/B testing. PayGuard is your safety net — run a quick test after every change.
You worry about checkout breaking but can't check it every hour. Let Pro do it for you. Sleep better.
Every app install risks breaking checkout. PayGuard catches it. Pair with StoreCheck for full protection.
Auto-monitoring every 30 min
Instant email alerts · Error screenshots
Uptime monitors ping a URL. A 200 OK response doesn't mean checkout works. PayGuard actually clicks through the checkout flow — add to cart, fill details, reach payment. We find problems uptime monitors miss.
No. All testing runs server-side via Puppeteer — a real browser on our infrastructure. We request read-only permissions and never touch your theme or code.
Absolutely. StoreCheck is a full-store diagnostic (5 dimensions, 10 seconds). PayGuard is dedicated checkout monitoring. They complement each other — StoreCheck finds the problems, PayGuard makes sure checkout stays fixed.
