I self-host a couple of services, but I haven’t exposed anything outside my home network. I want to self-host my calendar, but not sure if I can do it without exposing it. Any recommendations on the best way to go about this? For those who do self-host a calendar service, how do you keep it secure?
Unless you live a very dynamic lifestyle that requires your calendar to be 24/7 synced, you can just use whatever server software you like, make it listen in LAN only, and have your devices sync when they’re at home.
DecSyncCC and Syncthing is another option.
