ChangeDetection - Monitor Changes on Any Website and Get Push Notifications

ChangeDetection is designed to track changes to any publicly accessible web page, and can be used for a variety of purposes, including monitoring news sites, tracking updates to government websites, and tracking changes to competitor websites. In this article, we will provide a detailed overview of ChangeDetection, including its features, benefits, and how it works.

How Does ChangeDetection Work?

ChangeDetection works by periodically checking web pages for changes. When a change is detected, the application sends an email notification to the user, alerting them to the change. Users can choose how frequently ChangeDetection checks for updates, with options ranging from every 5 minutes to once a day. Additionally, users can choose to monitor specific sections of a webpage, rather than the entire page.

Install ChangeDetection using Docker Compose

You can easily spin up an instance of ChangeDetection using this Docker Compose stack

version: '3.2'
services:
    changedetection:
      image: ghcr.io/dgtlmoon/changedetection.io
      container_name: change-detection
      hostname: changedetection
      volumes:
        - /docker/changedetection-data:/datastore
      ports:
        - 80:5000
      restart: unless-stopped

To use ChangeDetection, users first need to create a new monitoring task by entering the URL of the webpage they want to monitor. Users can then configure the monitoring task by selecting how frequently they want ChangeDetection to check for updates and whether they want to monitor the entire webpage or specific sections. They can also set up email or push notifications to be sent.
