Website and Webshop Monitoring
JANES Sentinel clicks through the important flows of your site and webshop every few minutes and alerts you when something breaks. A monthly service with its own client portal.
Does this sound familiar?
If any of these are true for you, we can help.
Your customers are the ones telling you that the cart or the payment is broken.
Something went down at night or over the weekend and you only found out in the morning.
An update or an app setting broke a flow and nobody noticed.
The homepage loads, so everyone assumes the shop is fine.
You cannot say how long the store was down last month.
Blank or broken pages show up and no alert is sent.
Most webshop outages are not full outages. The homepage loads and the server answers, while the cart, the login or the checkout page is broken. A simple ping does not catch this, but the customer does: they leave, and they say nothing.
This is why JANES Sentinel does not only check whether the server responds. It clicks through the store in a real browser the way a customer would: opens a product, adds it to the cart, starts checkout and reaches the payment page. It stops before payment, so a real transaction is never started.
It also compares screenshots of your key pages against an approved baseline, so a blank or broken layout surfaces too, not just an error message.
When something breaks, the alert arrives by e-mail or webhook with the failing step, a screenshot and the browser errors, so you can fix it instead of investigating it.
The service runs on its own at sentinel.janes.hu, with a client portal showing 30 days of results and the history of past incidents.
