What do people here think of Nebula? (lemm.ee)

I've been playing around with self hosting for file sharing, backups, and a handful of other ideas I might one day get round to. I like the idea of a mesh VPN and being able to, for example, connect a travelling laptop to a 'host' laptop nearby, though my only public ip is a VPS in another country.

Of all the options I found, I liked the look of Nebula most. Fiddly in some places, but it's working nicely for me, and I appreciate some of the simplicity of design.

I'm wondering if people here have much experience of it, though? My biggest concern is over its future. With,

  1. The Defined Networking site focusing on making money off it, and
  2. The Android app doesn't allow full configuration (including the firewall, so I can't host a website from a phone) but - I heard - does if you use Defined Networking's paid service for configuration,

makes me worry they might be essentially trying to deprecate viable FOSS Nebula in favour of a paid or controlled service.

Any thoughts? Insight?

  1. Biggest thing was actually the sign up options. What if I don't want my machines calling to Google or Microsoft to get access to Tailscale? I need to look up the other OIDC providers but don't know much about that yet.
  2. Then the fact of Nebula being fully open source and fully on my machines. (Though that's a little undercut by the Android problem being solved only by their managed service).
  3. Headscale gave me an impression of being more complicated to set up and maintain. Haven't tried it yet, that was just my feel when I chose which one to try.
  4. More recently, I saw Nebula's interesting post on performance benchmarks. At high throughout Tailscale can be better for CPU but heavier on memory. Hopefully at my sort of very low throughout it's small on memory but if I'm squeezing a client into a cheap vps alongside nextcloud and other things, memory use is more concerning to me than CPU... I wonder how much memory Tailscale uses when not doing much.
