I’ve just been trying both and the Tailscale web dashboard is a lot more polished. Tailscale also uses wireguard instead of something proprietary. But I’m wondering if the zerotier iphone app might use less battery because I’ve heard tailscale has a problem with that.

It’s not just about trusting the code (which anyway isn’t a small task to review it, and all future PRs, and run your own builds from reviewed code) but also there are some people who will avoid Russian developed stuff at the moment for moral reasons, you know, because of the whole Ukraine thing.

This might not be a factor you care about, but Adguard is developed in Russia.
