I second this, and want to highlight that only recently I learned about this similar project called netbird. I tried it, and it looks and works very similarly from the first glance. However, Magic DNS like feature did not work for me, for some reason. Maybe I need to do something, e.g. to enable it. More likely there are others, similar projects, but I’m not aware of them. By this point I stayed with Tailscale, but in any case, I see such project as of tremendous help for a self-hoster.
