ChangeDetection
A self-hosted Monitoring & Analytics app you can run on your own server.

Its public repository on GitHub currently shows 33.8K stars, a useful signal of community interest. Repository activity was last recorded on Sep 11, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Monitoring tools should be boring and reliable. Start by instrumenting one server or site, set alert thresholds conservatively, and confirm notifications actually reach you. Self-hosted analytics keeps visitor data off third-party platforms, which simplifies privacy compliance.
Like every project listed on SelfHosted, ChangeDetection is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
