**ZeroTier** makes it easy to securely connect devices, servers, cloud VMs, containers, and apps everywhere and manage them at scale. Now, with **libzt** you can bake this ability directly into your app or service using your preferred language or framework. We provide a BSD socket-like API to make the integration simple.
