The problem
200 OK doesn't mean anyone can buy.
77% of checkout failures happen while the site is up. The server answers, uptime tools stay green, and orders stop.
These are the failures they miss, named the way MageSentinel reports them.

How MageSentinel compares
We don't simulate checkout. We buy.
APM tools watch your servers. Uptime monitors watch whether the URL answers.
MageSentinel watches whether a customer can complete a purchase, and with the store connector it goes all the way to an order in your admin.

01What does MageSentinel actually do?
It buys from your store on a schedule. A real browser opens your storefront, finds a product, adds it to the cart, fills in checkout and goes as far as the plan allows — up to placing a real test order. If any step fails, you get an alert with the evidence attached.
02How is that different from uptime monitoring?
Uptime monitoring asks whether your homepage responds. It answers yes while your payment step returns a 500 and nobody can buy anything. MageSentinel fails in exactly the cases that cost you orders, because it walks the same path a customer does.
03Does it support Hyvä Checkout and one-step checkouts?
Yes. MageSentinel is built for the Magento 2 checkout: Luma, Hyvä Checkout and one-step checkouts, as well as WooCommerce. There is no checkout script to write; the browser finds the steps on its own.
04How does it compare to Datadog, New Relic or Checkly?
Those are general monitoring platforms: you write and maintain the browser script for your checkout yourself. MageSentinel does one job for Magento and WooCommerce stores out of the box — it walks the checkout, checks prices, shipping, totals and payment, and names the step that broke. Plans are counted in stores, not test runs.
05Do I have to install anything on my store?
No. The checkout monitor drives your storefront from outside, like any visitor, so you can be running within minutes of signing up. The optional Magento module or WordPress plugin adds store-side diagnostics — platform version, active modules or plugins, recent errors — which turns "checkout is broken" into "checkout is broken because of this".
06Will the test orders pollute my real data?
Real test orders are opt-in and off by default. When you enable them you choose the product, the customer details and the payment method used, so the orders are recognisable and easy to filter or cancel. Every paid plan can place them once the store connector is installed, so the order is cancelled straight after; the Free plan stops before order placement.
07Can I try it before paying?
Yes. Every new account gets a 14-day free trial with no card required. When the trial ends without a paid plan, the store moves to the Free plan — one store, a full checkout once a day, HTTP checks every 5 minutes — and your history is kept. Nothing is ever charged unless you choose a plan yourself.
