A Checkly alternative for e-commerce checkout monitoring
Checkly is a strong developer tool: you write Playwright tests and it runs them on a schedule. For a store owner or an agency the question is different. Who writes the checkout script, who fixes it after every theme update, and does it actually place an order?
What Checkly is built for
As published on its pricing page (checked 2026-10-19), Checkly browser checks are Node.js scripts using Playwright, and plans meter browser check runs per month: 1,000 on the free Hobby plan, 3,000 on Starter and 12,000 on Team, with overage priced per thousand runs. It also offers API checks and uptime monitors.
That model suits engineering teams that already write Playwright tests. The checkout script is yours: the selectors, the test product, the payment step and the handling of every theme, plugin or extension change.
What changes for a store
A store checkout is not a stable test target. Themes change, payment plugins update, a shipping method disappears for one country. A script that clicked through last week fails on a renamed button, and someone has to tell a broken store from a broken script.
MageSentinel ships the checkout flow instead of asking you to write it. A real browser finds a product, adds it to the cart, fills checkout, picks shipping and payment, and on plans with test orders places a real order, confirms it in your admin and cancels it. It handles Magento 2 Luma, Hyvä and common one-step checkouts and WooCommerce classic and block checkouts without custom code.
When a check fails
A generic script failure is a stack trace and a screenshot. MageSentinel names the step and one of its failure codes, such as PAYMENT or PLACE_ORDER_FAILED, gives the likely cause, and attaches the screenshot and network log. One incident opens per problem, not one alert per run.
Find out your checkout broke before your customers do.
Real checkout checks for Magento and WooCommerce · 14 days free · no card requiredHow pricing compares
Checkly counts runs; MageSentinel counts stores. A checkout every 30 minutes is about 1,440 runs a month per store, which on a run-metered plan adds up as stores grow. MageSentinel Solo is €7.90 a month for one store, Starter €39 for five and Agency €149 for twenty, with checks every 30 minutes (every 15 on Agency). Every plan has a 14-day free trial, no card.
If your team already lives in Playwright and monitors far more than a shop, Checkly is a good fit. If what you need is to know that customers can buy, try the free Magento checkout test or WooCommerce checkout checker on your own store.
Common questions
Does Checkly support real e-commerce test orders?
Only if you script them yourself in Playwright. MageSentinel places, verifies and cancels a real test order as a built-in step on plans that include test orders.
Do I need to write code to monitor checkout with MageSentinel?
No. Enter the store address; the checkout flow for Magento and WooCommerce is built in.
Is MageSentinel cheaper than Checkly?
It depends on volume. MageSentinel is priced per store, not per run, so frequent checkout checks on several stores usually cost less.
