headscale VS nebula-mesh-admin

headscale - Open source implementation of Tailscale control server. Can be used with Tailscale's official open source client. Written in Go.

Headscale

You can always use headscale. https://github.com/juanfont/headscale

One more thing, you can host Tailscale Control Server yourself if you want, which is a plus.

https://github.com/juanfont/headscale not to mention but Tailscale has a very good culture, I’m sure they would give notice if they pull the rug. There are also many alternatives such as Zerotier and more are showing up every day and open source options.

How about self-hosted Tailscale, known as Headscale

Would be nice if https://github.com/juanfont/headscale can be managed by the Tailscale operator.

You can run your own "head scale" control server and use their clients with it: https://github.com/juanfont/headscale

Requires a lot more setup, but it is an option. I've been self-hosting headscale for some time and it is quite stable.

There's an alternative to tailscale service called headscale https://github.com/juanfont/headscale (CLI only server compatible with official tailscale clients)

Nebula is great - super simple to set up and get started if you have a VM to use as a lighthouse. Lots of cloud providers free tiers are have enough resources to host a lighthouse as well.

Certificate management is its one weakness at the moment. There are a growing number of projects floating around attempting to solve that though:

As other have suggested, Nebula (https://github.com/slackhq/nebula) is pretty elegant. It has groups-based access built in which is extremely convenient.

You can bolt-on SSO fairly easily - just create a certificate signing service. I created https://github.com/unreality/nebula-mesh-admin in a weekend, so its fairly easy to add a SSO flow in.
