Yeah, I only didn’t mention this because it’s theoretically possible for Tailscale to discontinue support for that and break compatibility in the clients if they decided they want you using their stuff.

There are self-hosted overlay networks. They may be harder to set up, but you prevent your infrastructure from being reliant on the ticking timebomb that is VC money. I’ve heard about:

• Nebula
• Netbird

But I’m sure there are others.
