I didn’t know NetBird existed. I may switch to it because it seems to be literally the same as NetMaker

NetMaker is like Tailscale. It uses Kernel wireguard unlike Tailslace which uses user space wireguard.

The only downside is that you need to pay for it or you can host your own server (but is kinda tricky to do)

Yeah that makes no sense lol. Who needs MAC addresses to debug and fix bugs? No one.
