Would be great if someone made something with the polish of Tailscale and made it completely free and open source, but I don't think it is happening any time soon. Wireguard itself has been an unbelievably great gift to the whole IT ecosystem and Jason will forever be cemented in my hall of fame.

But he did intend for Wireguard to be used in all sorts of solutions and Tailscale is one of them.

Tailscale apps themselves are open source for open source platforms (linux, android) and the 3rd party management server Headscale is open source, enabling you to maintain control.
