Changedetection is a self-hosted change monitoring of web pages. Know when web pages change! Stay on top of new information! Live your data-life pro-actively instead of re-actively, do not rely on manipulative social media for consuming important information. Know when Government department updates (changes are often only on their websites) – Local government news (changes are often only on their websites) – New software releases, security advisories when you’re not on their mailing list – Festivals with changes – Real-estate listing changes.
