I'm wondering if anyone has used headscale? https://github.com/juanfont/headscale

I just started using tailscale but I don't like the fact that the keys lie on something I don't control, so I was looking for a way to host my own tailscale like site and came across this. this looks like what I was looking for so I was wondering if anyone has tried it and find it a viable and stable for the use case for a small home network or two
