Biggest thing was actually the sign up options. What if I don’t want my machines calling to Google or Microsoft to get access to Tailscale? I need to look up the other OIDC providers but don’t know much about that yet.
Then the fact of Nebula being fully open source and fully on my machines. (Though that’s a little undercut by the Android problem being solved only by their managed service).
Headscale gave me an impression of being more complicated to set up and maintain. Haven’t tried it yet, that was just my feel when I chose which one to try.
More recently, I saw Nebula’s interesting post on performance benchmarks. At high throughout Tailscale can be better for CPU but heavier on memory. Hopefully at my sort of very low throughout it’s small on memory but if I’m squeezing a client into a cheap vps alongside nextcloud and other things, memory use is more concerning to me than CPU… I wonder how much memory Tailscale uses when not doing much.
