Tailscale has its use when you are behind CGNAT and don’t want to VPS a Wireguard server somewhere with a static IP, other than that, it has no use in my opinion. I’m fully aware that I get downvotes from people who praise the zero trust principals of Tailscale and all the rest, but they always forget that you can do zero trust since decades with any network equipment (VXLAN) and add Wireguard to the mix.

People just forget that all Tailscale is is a fancy GUI for managing Wireguard. That’s it.

Wireguard lacks a lot of user management features so you need a service like Tailscale to handle that, but everything zerotier does is something you can already do in wireguard, just simplified.
