I switched from Tailscale to Netbird purely because of Tailscale's bizarre pricing tiers - I wanted just the SSH features, with multiple users, but the paid tier up from free didn't include the SSH features.

I think Tailscale would've fit my needs perfectly fine, but the management makes access control and grouping dead simple in netbird. It also generates a nice little map of your peers, their groups, and connected nodes etc. Quick visual on your topology.
