About
The best and simplest self-hosted free open source website change detection monitoring and notification service. An alternative to Visualping, Watchtower etc. Designed for simplicity - the main goal is to simply monitor which websites had a text change for free.
Features
- Lots of trigger filters, such as "Trigger on text", "Remove text by selector", "Ignore text", "Extract text", also using regular-expressions!
- Target elements with xPath 1 and xPath 2, CSS Selectors, Easily monitor complex JSON with JSONPath or jq
- Switch between fast non-JS and Chrome JS based "fetchers"
- Track changes in PDF files (Monitor text changed in the PDF, Also monitor PDF filesize and checksums)
- Easily specify how often a site should be checked
- Execute JS before extracting text (Good for logging in, see examples in the UI!)
- Override Request Headers, Specify POST or GET and other methods
- Use the "Visual Selector" to help target specific elements
- Configurable proxy per watch
- Send a screenshot with the notification when a change is detected in the web page
