Software tools

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.

Client

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.

Controller

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]
