A Shopwarden alternative: testing WooCommerce checkout from outside the store
Shopwarden is a WooCommerce monitoring service with a free plan. Its checkout tests work through a plugin that connects your store to the service. That is a real design choice with consequences. Here is a fair comparison with a monitor that runs entirely from outside.
What Shopwarden offers
From its WordPress.org listing: it checks uptime, uses robots to walk important flows such as checkout, and watches plugin versions. The plugin lets the service hook into WooCommerce, gather metrics and keep its test orders out of your order list. There is a free plan and a $29 Pro plan. Details such as check frequency are not on that page, so confirm them on its site.
Inside versus outside
A plugin-based approach knows things about your store that an outside visitor cannot, such as plugin lists and order metadata. It also has to be installed, kept updated and trusted with access to WooCommerce.
A hosted browser check needs nothing installed to start. It sees the store the way a customer does, through the public site, so a broken theme, a blocked script or a missing payment box shows up exactly as it would for a shopper. MageSentinel works this way; an optional connector adds root-cause data such as installed modules and recent errors, but checking never depends on it.
Price and limits
A free plan is a good way to try the idea. Compare what it includes with what you need: how many stores, how often checks run, how long evidence is kept and how many alert channels you get.
MageSentinel Solo is €7.90 a month for one store with checks every 30 minutes; Starter is €39 for five stores. Plans count stores, not flows, and work the same for Magento.
Which to pick
If you want a free start and are comfortable with a plugin, Shopwarden is a reasonable first step. If you run several stores, mix Magento and WooCommerce, or want the test to be independent of the store it judges, a hosted outside check fits better. Running both for a week on the same store is the quickest way to compare. MageSentinel has a 14-day free trial with no card. See also WooCommerce checkout monitoring tools compared.
