You can selfhost it with headscale (the server). It’s really simple to set up and use. I’m also considering moving to zerotier because a) it’s completely opensource and b) the wifi management software I’m looking into (openwisp) has native integration
good to know, thank you for the insights! Tbh Tailscale/headscale has been quite stable, so maybe I’ll stay were I am. Or move to nebula because why not? :D
