Topic per title, basically.
For me: after setting up all the integrations and fall overs using the arr stack and Jellyfin (inc Sabnzdb etc)… I keep circling back to Nova video player.
https://github.com/nova-video-player/aos-AVP/releases
It’s arguably not even self hosting…but there something undeniably cool about sticking a USB stick into a router, installing a single app on your TV and boom, done. EDIT: of course, it can consume the *arr stack, integrate with Ombi etc
IOW, I really like stuff that simple to set up and punches above its weight class.


apart from the usual suspect like, Jellyfin+Plex (still have some straggler users that need to upgrade their players for JF to work properly), Immich, nextcloud etc, I really like running Birdnet-Go. I give it my CCTV camera feeds and it uses a NN to identify birds it hears.
I get statistics about species heard around the property, charts to correlate detections to seasons and weather, and some interesting info about rarer species that I didn’t know were in my area. Every morning I check it to see if there was anything new recorded.
it doesn’t really have a purpose, though the data can be submitted to larger databases, but it’s just a nice thing to have.
EDIT: Also Vaultwarden, forgot about that, super happy to be hosting my own password manager instead of trusting (and paying for) companies like Dashlane to host it like I used to.
bringing you joy is its purpose, and that is valid.
