They have a public instance you can use but if you’re going to have things like location tracking and device wipe enabled then it’s probably better to self host.

Lots. Immich, Jellyfin, Ollama, Homeassistant, Frigate, Nextcloud, Navidrome, *arr stack, Find my Device Server, various monitoring/logging tools (mainly Grafana stack), etc.

Totally overkill for my use case but it’s for learning as well since I’m starting to use K8s at work.

Recently migrated my homelab from a one node docker compose stack to a dual node k3s cluster, so this looks pretty interesting.
