Another similar project to Tailscale, for those in the market:<p><a href="https://github.com/slackhq/nebula" rel="nofollow">https://github.com/slackhq/nebula</a><p>Crazy simple, fully open source, trivial to self-host. Maybe not as featureful as Tailscale, but imo that can be a feature unto itself.
