Thank you for your insight, I’m assuming the only public part is the UI and coturn (the bit that enables two clients between firewalls to hole-punch)?

Netbird you can still run unlike tailscale with headscale right?

At least hope the backend can be fully ran ?

I’m unsure if it has been mentioned, but a similar tool which is open source (you can run the backend unlike tailscale), netbird

https://netbird.io/

Similar in which regard? Containers can be covered by this, but I’m assuming you mean for things like charts?
