All kinds man. I have a pretty ridiculous homelab set up simply because of who I am as a person (and engineer).
My data (~120TB) is stored on a Synology NAS and I have a r610 with dual Xeons 32 threads and 192GB of RAM which does my compute. My service stack is all in Docker.
For services I have:
- Wireguard VPN for connectivity away from home
- Bitcoin infrastructure (core, lnd, lnbits, mempool, explorer, joinmarket)
- Matrix/Synapse for encrypted & private comms
- nostr-rs for Nostr relay
- Hugo static site generation for several different sites/blogs I run
- Pihole for blocking trackers/malicious things
- Documents, photos, drive are all Synology because their software is really good
- Sonarr, Lidarr, Radarr stack for media
- Plex for video consumption
- Navidrome for audio media streaming
- Vaultwarden for password management
- Gitea for code repo
- FreshRSS for RSS fetching
- Hauk for location sharing with friends/family
- ihatemoney for expense sharing/tracking
Those are my most used. There's also a smattering of other things I'm POC'ing or just playing with not really worth mentioning.
