Your devices will connect to each other peer-to-peer (even behind complex NATs) with no manual configuration, subject to ACLs you centrally manage. It just works.

People sometimes dismiss Tailscale as "just" a WireGuard orchestrator, but it's actually much more than that - From a product perspective, WireGuard is just an implementation detail.

It's a mesh VPN, so peers communicate directly without additional delay.

I opted for Netbird myself because Headscale's UI felt too basic for me back then. Has that improved over the years probably?

Tailscale's value prop is "Wireguard that the merely somewhat-technically-inclined can set up and manage unassisted". Across tons and tons of clients (my AppleTVs connect to my Tailscale network, this took maybe a minute to configure—and they can act as gateways)

Some do not want/have a fixed IP address or anything listening on their home network.

Tailscale or having Headscale hosted somewhere else allows you to do that.
