I'm currently comparing it with pangolin and headscale for my small scale company infrastructure access. Been running headscale for my own setup for a while but maybe netbird or pangolin might be better for real production.
That said, it seems focused on client-to-site (newt) connections, and I don't see support for client-to-client connections like Netbird’s SSH access. Also, their Private Resources don't seem to support TLS termination yet. (Correct me if I’m wrong!)
In my case, I have a k3s cluster running on Netbird with a Traefik ingress for TLS termination inside my home network. Thanks to netbird's P2P nature, traffic stays entirely local as long as I'm on my home WiFi. (I suppose one could achieve the same with a Netbird + Caddy + DNS-01 setup, too.)
