If you were looking for an open source, self-hosted implementation of the Tailscale control server (as far as I know, that is the only portion of tailscale that tailscale keeps proprietary, and this is the best open source implementation of it).
Edit: wow, this project has really grown from when I last saw it. It is able to configure the vast majority of tailscales base featureset such as ACLs, magic DNS, taildrop file sharing, and so much more. Incredible.
