I run this in a Docker container on my home network without connecting it to their cloud platform (despite their - increasingly strident, it feels - "encouragements" to do so). It's very powerful, and the majority of low level configuration is done via text files. But 99% of it is automatic.

The UI is unique. It's a single, long and scrollable page, which may be an issue for some.

There are other tools out there, too. I previously used one that integrates Grafana, Prometheus and Node Exporter, which is more complex to set up and configure.
