Know it before your customers do.

A real browser clicks through checkout, login and forms every few minutes, and alerts you before your customers notice a problem.

Why JANES Sentinel?

Loading is not enough. What matters is that your customer gets through to the payment page.

Uptime checks tell you that the homepage answers. JANES Sentinel tells you that the cart, the checkout and the login still work – the functions that make you money.

What we check for you

01. Check

Availability check

Every few minutes we request your pages and APIs, like a browser does, only faster.

  • The HTTP status code, e.g. 200
  • An expected text in the response
  • Response time and timeout
  • Redirects and custom headers, e.g. API tokens

It catches it when the server returns an error, does not answer or the page loses its content.

Incidents without false alarms

Thresholds filter short network blips. An incident opens after repeated failures and closes by itself on recovery.

Instant notifications

Email and signed webhooks when something breaks – and when it works again. Not one mail per failed check.

Diagnostics for developers

The failed step, a screenshot, console errors and failed network requests – everything to fix it fast.

Availability you can show

Your clients see the availability of the last 30 days and the incident history in their own portal.

How it works

Three steps to sleeping well

01. Step

Register

Create your client account and tell us which websites and functions matter to you.

Takes a few minutes
02. Step

We set up the checks

We build the browser flows and HTTP checks of your critical paths – stopping before real payments.

We do the work
03. Step

You get alerted

If checkout breaks at 3 a.m., you know it at 3:05 – with the failed step and a screenshot.

Day and night
Client portal

Everything your client wants to know – on one page.

Availability of the last 30 days, the status of every monitored function and the incident history – in plain language, without stack traces.

  • Availability you can show
    Day by day for the last 30 days, based on real checks.
  • Every function at a glance
    Homepage, cart, checkout: green when it works, red when it does not.
  • History of failures
    When something broke, how long it took and when it was fixed.
