Detect regression
after implementation.

The Monitoring module periodically checks chosen URLs and reports meaningful changes: downtime, HTTP errors, HTTPS issues, Insight score regressions and new technical risks. It is early warning — not full infrastructure observability or a 24/7 uptime guarantee.

A one-off audit shows how things are now. Monitoring shows when something got worse.

Sites break for more than big releases — a CMS update, expired certificate or new marketing script is enough. The module compares results over time and flags regressions — with no promise it fixes problems or replaces DevOps.

From setup to alert.

Four steps from a URL list to a response — without checking everything by hand every day and without a full observability stack promise.

Availability Scan

HTTP status, 4xx/5xx errors, redirects and key page responses.

URLs to watch

You add the homepage and key pages. Monitoring checks availability, HTTP status and basic technical signals — on a schedule, not in real time.

Scheduled scans

Insight compares current results with previous measurements: Performance, SEO, Accessibility, Security and Ecology. You see whether something dropped after a deploy or a new issue appeared.

Alerts and history

Meaningful changes land in an event list with date and context: 500 errors, accidental noindex, expiring certificate, score drop. Not every alert is critical — the module helps separate urgent from observational.

Respond and verify

After a fix you return to history and check whether the issue cleared. Monitoring does not repair the site — it helps you notice sooner when attention is needed.

System status

Up · degraded · down — no guessing.

Every monitored URL has an unambiguous status and check history. You see not just "is it up", but response times and when the status changed.

  • Statuses: up · degraded · down
  • Response time on every check
  • Status change history
cometweb.io 182 ms Up
app.cometweb.io 244 ms Up
api.cometweb.io/v2 612 ms Degraded
blog.cometweb.io 201 ms Up

SSL certificate

The certificate will not expire on you at 3 a.m.

Certificate validity and trust chain monitoring with warning thresholds. You get the signal early — before browsers start scaring your client's customers.

  • Certificate validity and trust chain
  • Warning thresholds: warning and critical
  • An alert before users see it

JavaScript errors

A synthetic browser catches what HTTP checks miss.

The page renders in a real browser (Playwright) and monitoring collects console errors, exceptions and failed resources. A form can look fine and not work — this catches exactly those cases.

  • Browser render, not just an HTTP status
  • console.error · exceptions · failed resources
  • Catches "up but broken"
Playwright render · viewport 1440×900 · last check 6 min ago

SLA and alerts

An availability conversation grounded in numbers.

Uptime set against your SLA threshold: above, at the limit, below. Alerts go where you work — and a report with incident history is ready for the client meeting.

Instead of more separate scanners
one audit and a clear order of action.

One scan shows what is worth fixing. No card, no commitment — results in about 2 minutes.
