Changedetection.io

Changedetection.io is an open-source tool to monitor websites for content changes.

Description

It provides a simple way to track changes on any website and receive notifications via various channels (Discord, Slack, Email, etc.). It is highly useful for tracking price drops, software releases, or news updates.

When to use it

• When you want to monitor websites for content changes or price drops.
• To receive automated notifications when a specific page updates.
• For tracking software releases or news without manual checking.

When not to use it

• For high-frequency monitoring of rapidly changing data (consider specialized trading or scraping tools).
• If you need to monitor content behind complex, multi-step authentication that isn't easily scriptable.
