I am a huge proponent of Tailscale, and I've moved my entire stack into my tailnet. Even my steam deck.

"By making the Tailscale clients open, you can see that we don’t collect your private keys. And by making Tailscale’s DERP servers open, you can see that we can’t capture your encrypted traffic.

We hope that keeping this code open increases trust and transparency in Tailscale because anyone can review the code and see that Tailscale really works the way we claim."
