Jellyfin: An unfederated alternative to Plex, with some pros and cons. Very lightweight, customizable with plugins. Decent iOS and tvOS client from the devs.

Vaultwarden: Unofficial open-source fork of Bitwarden.

FreshRSS: Self hosted RSS + Atom reader, honestly the best way to read news ad free. I recommend using FreshRSS with lire if you’re on iOS.

I’m definitely looking into hosting PiHole down the line, and hopefully nextcloud once i get some more drives

There are multiple ways to evaluate usage. I’ll go with what I would guess is your desired measurement, things that I use intentionally (as opposed to things like dns, which just happen incidentally to other things or automation based things which are continuously running but not necessarily interacted with):

1. Mastodon
2. An app I’ve written to collect personal data
3. Jellyfin
4. Lemmy
5. Bitwarden (I pay to self-host as opposed to vaultwarden as the latter probably won’t have a security audit)
6. Freshrss
7. Linkding
8. Gitea
9. Archivebox
10. Mailcow

pihole, wireguard, qbittorrent, sonarr/radarr, Jellyfin, syncthing, NFS.

I've considered Airsonic but I haven't found a good client that looks good and doesn't behave weirdly. I had one launch about 500 threads trying to transcode the same song which ate up my CPU time on my server resulting in a stern e-mailing from my host.

1. DNS server, because everything depends on it
2. The Lounge - got like 7 people using it basically daily to chat
3. Lemmy, even though I'm the only one really actively using it.
4. E-Mail server, I don't get a whole lot of mail but it's a pretty important one!

Everything else tends to be a lot more idle, but I've also got NextCloud, an IRC server, soon a Matrix server, an internal VPN so all my devices can always talk to eachother no matter where they are.

Plex, PiHole, Photoprism, Home Assistant, Syncthing in a hub and spoke config, Caddy for reverse proxy, custom containers for: yt-dlp, restic, and rsync.
