I wrote a self-hostable control plane for Nebula (a Tailscale-like overlay networking tool), and have been using it for about a year: https://github.com/losfair/supernova

Built this because existing solutions like ZeroTier and Tailscale are trying to be too "smart" (auto-selecting relays, auto-allocating IPs, etc.) and do not work well for complex network topologies.
