WireGuard supports mesh as well, but it requires to manually configure all the keys and all the IPs on all devices.

There is wgsd, which supposedly makes WireGuard mesh networking easier, but I haven’t tried it.

Is this like Tailscale? Maybe closer to Headscale, as tinc seems to be completely self hosted.

I think the OP is looking for a decentralized alternative to something like Nord/Express/Mullvad to hide their traffic, and not a way to connect their devices together.
