ZeroTier charges by device. Tailscale charges by user.
ZeroTier is a lot cheaper if you only need to connect a single device for each employee. It gets a lot more expensive if you have a lot of devices.
Tailscale is the opposite. Cheaper if you have a lot of devices, but if each employee only has a single laptop which needs to be connected, then it's a lot more expensive.
Tailscale's documentation is way better and walks you through it like a beginner. ZeroTier's documentation assumes you are already knowledgeable about networking.
