I use it to replace ssh tunnels. I used to have a couple of ports open on my office router I would ssh through. I closed those off and use tailscale on a single machine in my office as a subnet router. Now when I am at home or travelling, I have direct access to my test database, VMs and remote desktops without having to tunnel those ports. When they say zero conf they mean it. Truly impressive product. I could get away with the free version but I paid for it I was so impressed.
