ZeroTier is software that allows you to create virtual networks between your devices using a simple central web interface. You could compare these virtual networks to setting up a VPN on your Raspberry Pi. However, the provisioning experience is far simpler, especially when managing multiple devices.
Connections are made between each of your devices using a peer-to-peer network. These connections are secured using end-to-end encryption to help keep your data secure and private.
In addition to running ZeroTier on a Raspberry Pi, you can also run it on most other devices, including phones. Furthermore, it can work on Linux, Windows, and macOS, meaning you can create a virtual network without worrying whether your device can join.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
