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
