Prometheus
A self-hosted Monitoring & Analytics app you can run on your own server.
Prometheus is a self-hosted monitoring and analytics tool that you run on your own server instead of renting it as a cloud service. It is a practical pick for homelab users and teams who prefer owning their tools over renting them.
The project is developed in the open via GitHub, where it has earned 66.0K stars from the community. 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, Prometheus 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.
