MageSentinel
Synthetic checkout monitoring for Magento

Know when your checkout breaks —
before your customers tell you.

MageSentinel runs a real add-to-cart-to-order flow against your Magento store on a schedule, catches silent checkout failures other monitors miss, and tells you the likely cause — not just that something went red.

01 Detect

The same checkout path your customers take — on a schedule.

Not a ping, not an HTTP 200 check. MageSentinel drives a real browser through product → cart → checkout → shipping → payment → optional order placement, asserting the actual business result: SKU, price, quantity, totals.

  • Resolves selectors across Luma, Hyvä Checkout, and one-step checkouts — no theme-specific code.
  • Plays through consent banners, promo popups, and chatbot widgets that break real checkouts.
  • Schedules from 30-minute checkout runs on Solo up to every 5 minutes on Scale, with state-change alerts — never per-check noise.

02 Explain

Every failure ships the likely cause — not just a red badge.

MageSentinel correlates the run’s evidence into ranked causes with confidence, impact classification (all-customers / some-customers / unknown), and a concrete next step. And because UNKNOWN is a real first-class outcome — never forced into PASS or FAIL — its alerts stay trustworthy enough to act on unread.

  • Stable product-level failure codes (PLACE_ORDER_FAILED, CHECKOUT_SESSION_ERROR, PAYMENT_NO_METHODS, …) — never raw exceptions.
  • Optional Magento connector module adds root-cause data: version/mode, third-party modules, cron health, queue depth, logs.
  • State-change alerts with a 60-minute cooldown — you hear about a break once, not on every check.

03 Prove

Screenshot, trace, network log — handed straight to a developer.

When a check fails, MageSentinel captures the full evidence automatically: a viewport screenshot, a Playwright trace, a redacted network log, and console errors. Everything is redacted at capture time — no cookies, auth tokens, CSRF tokens, passwords, or card numbers ever reach disk.

  • Failure context written to JSON the moment a step breaks — failure code, store URL, the page URL at failure time.
  • Network summary ranks the failing store-API call first, third-party ad pixels last.
  • Evidence retained per plan — from 3 days on Free to 90 days on Scale.

Why this exists

The failure you never heard about

Checkout breaks quietly. These are the mornings MageSentinel is built to prevent — written as scenarios, not as customer quotes.

The Friday night deploy

A payment module update breaks card payments at 21:00 on a Friday. Nothing goes down: the store loads, the catalogue works, the cart fills. The first person to notice is a customer on Monday, or nobody at all. A synthetic checkout notices at 21:14, with the failing request already captured.

Green dashboards, zero orders

An agency watches fourteen client stores. Every uptime tool reports green, because every store answers 200. One of them cannot take a single order — the shipping step never renders. Pinging the homepage cannot see that; walking the checkout can.

The evidence, not the alert

Knowing checkout is broken is the easy half. A screenshot of the step that failed, the network log, the console errors and the exact request live in the alert itself, so the work starts at “here is what happened” instead of “can you reproduce it?”.
