Adding to the cool stuff in Tailscale, I found out Tailscale supports go/ links.

I loved using go/ links at Google, so being able to use them for my own services on my tailnet is great. It was easy to get the container running on my host using docker run, and now I don't have to futz with IP addresses or ports. It points just as easily to external addresses to, so I also have go/ links for my PikaPods (like this one).
