Tailscale is a vpn that allow you to connect to your own self hosted services without exposing ports over the internet.
It work amazing well. I read about self hosting headscale that works as a Tailscale coordinating sever for better security. It sounds great, but all I want to do is access my Jellyfin server and truenas box over the internet without exposing ports. I do not need the headache of maintaining another service. It look easy to install and set up. I rather not waste my precious free time on trying out alternatives when Tailscale does everything I need.
