I just recently started playing around with an old pc as my homeserver and am curious of any recommendations for lesser known self hostable foss software that you would recommend

  • Yacht is a great UI for starting a container, especially for self hosting, there are a good amount of tutorial online.

    I personally also host

    • syncthings that will sync my app settings on the phone, and push it to my cloud drive,
    • pi-hole to block trackers. I generally let ad through, but not trackers.
    • jellyfin for media library
    • transmission for (cough, cough) seeding fedora, mint and other free and open source, and 100% legal stuff.
    • home assistant for automations.

    Some other things you can try:

    • a home Minecraft server, not exactly FOSS, but if you are into it, you should do it.
    • Nextcloud for syncing photo and documents, but remember to keep a offsite backup.
