ZeroTier is a network virtualization system that combines the capabilities of traditional VPN systems and software defined wide area network solutions. Some example uses of ZeroTier include: accessing devices on a home network (for example, network attached storage, home automation, and printers) from anywhere; creating a virtual LAN across several households to play network games; routing traffic destined for the internet through a VM running on a cloud provider; routing traffic received at a VM on a cloud provider to an internal machine on a private network; or connecting systems running on a variety of cloud providers as if they were in a single data center. The ZeroTier manual located in the Support section of the site contains a detailed technical description of how the software works along with a number of example configurations. The ZeroTier Knowledge Base contains additional tutorials and "Getting Started" guides. The ZeroTier site offers installers for Windows, macOS, Linux, and FreeBSD desktops along with installers for Android and iOS devices. On the free "Basic" service plan, users can create networks with up to 50 members.
