WebTrackr is a Chrome browser extension that monitors webpages for changes and alerts you via Email, Slack, or Telegram on detecting a change. It works for both websites and web pages.

To get notified when a website or web page has been updated, simply install the WebTrackr extension on your device and start monitoring for changes.

To start tracking a web page for changes, all you need to do is visit the URL you want to monitor. There you can choose from the different settings, such as whether you want to track every change, only changes in the last 24 hours, or changes for every week or month.

After you have set up the first web page you want to track for changes, you can visit the website's dashboard. There you can view and manage all items that you're tracking along with the complete change history/archives for that item.
