Cheap Vps: mainly seafile (file sync) and prosody (jabber/xmpp). I want those always available from everywhere.
Living room has a small passively cooled n150 which runs almost 20 services, from home assistant and jellyfin, over paperless and navidrome, to some lesser known services (yamtrack, koito, grimoire). A bunch more, and I use them regularly, some more than others, but then adding a service without exposing it (my caddy lxc has 2 IPs, one port forwarded one internal only) is really cheap.
