Software tools[edit]

ZeroTier markets proprietary tools, which are licensed under a Business Source License 1.1,[7] intended to support the development and deployment of virtual data centers:

In 2021, the product line consists of the following tools:

  • ZeroTier One, first released in 2014,[8] is a portable client application that provides connectivity to public or private virtual networks.
  • Central, a web-based UI portal for managing virtual networks.
  • libzt (SDK), a linkable library that provides the functionality of ZeroTier One but that can be embedded in applications or services.
  • LF (pronounced "aleph"), a fully decentralized fully replicated key/value store.


The ZeroTier client is used to connect to virtual networks previously created in the ZeroTier Central web-based UI. Endpoint connections are peer-to-peer and end-to-end encrypted. STUN and hole punching are used to establish direct connections between peers behind NAT. Direct connection route discovery is made with the help of a global network of root servers via a mechanism similar to ICE in WebRTC.


Virtual networks are created and managed using a ZeroTier controller. Management is done using an API, proprietary web-based UI (ZeroTier Central), open-source web-based.[9][10] Using root servers other than those hosted by ZeroTier Inc. is impeded by the software's license.


ZeroTier One is available on multiple platforms and in multiple forms:
