Dffer – Get notified when a website changes

In plain words

Dffer monitors websites and sends notifications when they change. It's designed for people who want to track updates on specific web pages without manually checking them repeatedly. The tool automatically detects alterations to monitored sites and alerts users to the changes, making it useful for following news sites, job boards, pricing pages, or any web content that updates periodically.
