I gave up and just setup wireguard directly instead, I don't trust Tailscale either if that's their attitude towards privacy, it's permanently marred my vision of their product.

There also exists an open source implementation of the tailscale control server [1] that you could self host.
I settled on ZeroTier for now. Unfortunately, I don't think ZeroTier is my long term solution. Their self-hosted option comes with a plethora of caveats that make it basically unusable. And I'm always scared companies that offer free versions of their paid product will eventually neuter the free tier.
I'll be keeping an eye on headscale. Hopefully they get their mobile client situation in order.
Compare that to ZeroTier where I can just tell someone, "install this app and punch in this Network ID". Also, ZT lets me control the entire network firewall from a centralized place. Where Nebula is doing it on a per-client basis and requires new certs if device groups change.
I don't want to talk up ZT too much though. Their self-hosted option is a joke. There is no webui. You have to do everything via the API...including the firewall rules; And you have to write those rules in the non-human readable format that their webui abstracts away. Worse still, their mobile apps won't work with the self-hosted option. I used them to get something up and running quickly, but I'll probably end up on Nebula anyways.
There's a community developed one:
The software linked in the parent works with the mobile apps.
