Not GP. Probably less dependencies on github, e.g. actions which sometimes don't work. This way github is a "dumb backup".

I selfhost forgejo (gitea fork) on home sever (nuc), similar setup with tailscale. I was planning to setup git mirror on a remote VM for backup, but since I am the only one using it and have everything on dev laptop and remote backups of nuc server I didn't bother to do that (I know I still should).
