No one uses Nebula [1] developed by Slack?

> Nebula is a mutually authenticated peer-to-peer software defined network based on the Noise Protocol Framework.

It's self-hosted and I think it's a great alternative to ZeroTier, or Tailscale.

I believe its been powering Slack's overlay network for ~5+ years.

I used it for a while, but found it to be unreliable. Sometimes my Raspberry Pi’s became unavailable through the nebula network. I had to ssh into the Raspberry from home network and restart the nebula service. This happened once a week or so on Zero W, so I tried Tailscale. It was much easier to set up than Nebula and works better for me so far (3 months).

YMMV, of course.
