I tried both MQTT and just the plain HTTP variant, and I couldn’t get either to work. I’ve fully settled on the latter you mentioned, Traccar. it’s pretty much what I’ve wanted: self-hosted, easy to set up, beautiful web interface. Thanks for the suggestions!

for two reasons, I can’t use this.

1. Android. Me, my family. Our past phones were, our current phones are, and future phones will be Android phones.
2. I’m looking for whatever it may be to be OSS and self-hostable (if the community name didn’t give that implication away)

OwnTracks setup was a bit confusing to me and I never got it working. traccar looks pretty nice though, I’ll check it out!

usually in your router settings you can change local DNS settings. you can set your domains and subdomains to point to your server’s local IP.

although definitely not as configurable, I like the “set it and forget it” idea of DockoVPN

Nearly all of them. Nextcloud, Jellyfin, Vaultwarden, Spacebar, and 2fAuth, all set behind an NGINX Reverse Proxy, SWAG. SWAG made it very easy to set up https and now I can throw anything behind a subfolder or subdomain.

Playnite. Combines all games from all connected launchers into one and configurable/themeable to your hearts desire
