Changedetection.io

Changedetection.io is the best and simplest free open-source website change detection, website monitoring, restock monitoring, and notification service.

Key Features:

• Numerous trigger filters, such as "trigger on text," "remove text by selector," "ignore text," "extract text," and more, using regular expressions!
• Locate elements using xPath (1.0) and CSS selectors; easily monitor complex JSON using JSONPath or jq
• Switch between fast non-JS and Chrome JS-based "fetchers"
• Track changes in PDF files (monitor text changes in PDFs, as well as file size and checksum changes)
• Easily specify how often to check sites
• Execute JS before extracting text (great for login scenarios; see examples in the UI!)
• Override request headers, specify methods like POST or GET, etc.
• Use the "visual selector" to help locate specific elements
• Per-watch configurable proxy
• Send notifications with screenshots when changes are detected on a webpage
