Paste a URL. MonitorCat highlights what to watch.

No CSS selectors, no guesswork. MonitorCat opens the page in a real browser, highlights what is worth monitoring and pre-fills the monitor name — so you are set up in a couple of clicks.

  • Smart suggestions

    MonitorCat highlights what is worth tracking on the page — the price, title, stock and more.

  • Or select it yourself

    Prefer to choose? Click the exact element on the rendered page. No CSS selectors.

  • Named automatically

    Your monitor is named from the page, so your list stays readable without manual tidying.

How it works

Up and running in three steps

1

Add your URL

Enter the URL of a publicly accessible webpage you want to monitor.

2

Choose what to monitor

MonitorCat suggests what to track, or click the element yourself: a price, a content section, a whole page or page availability.

3

Set the schedule

Choose a check interval. MonitorCat records each run and emails you when a scheduled check detects the configured change.

Straightforward monitoring

Simple plans, clear features

Set a schedule, let MonitorCat check the page and receive an email when it detects the change you configured. Recent history gives you a clear record to come back to.

About MonitorCat and its approach
  • Start with 1 active monitor on the free plan.
  • Choose intervals from 10 minutes to 24 hours, subject to plan limits.
  • Receive email notifications when scheduled checks detect configured changes.
  • Checks run in a real browser, so JavaScript-heavy and bot-protected pages still load.
  • Pages behind a login or showing personalised prices remain out of scope.
