OS and Device Compatibility
ZeroTier is lightweight, portable, and compatible across all major platforms and architectures. It typically consumes less than 16 MB of memory, only about 1 MB of storage, and even has a low-bandwidth mode for IoT applications. It supports 32-bit ARM (arm32), 64-bit ARM (arm64), 32-bit Intel (x86), 64-bit Intel (x64/amd64), MIPS, and s390x. You can run it on Linux, macOS, Windows, iOS/iPadOS, Android, and FreeBSD. You can run it on Routers, Network Attached Storage, and we have solutions for when you can't install ZeroTier on a small IoT sensor.
We generally adhere to manufacturer life-cycles for feature support of each platform but will attempt to backport important security updates to versions for older operating systems where possible.
-
Our most recent client can still be run on tiny single-board computers like the original Raspberry Pi made over a decade ago and all versions of ZeroTier are backwards compatible.
-
ZeroTier is currently single-threaded so devices with more than two cores typically will not offer significant performance gains. Future versions of ZeroTier will introduce multithreading.
-
While ZeroTier will operate on very low-power hardware (e.g. a single core 32-Bit ARM running at 600Mhz without AES hardware acceleration (AES-NI)), its performance will suffer.
We recommend the following for a happy ZeroTier experience: >=1GHz CPU with at least 2 cores, and AES-NI.
If you're planning on embedding ZeroTier in a product such as a router, network attached storage or some other IoT application we see that our partners have a better experience with 64-bit ARM as opposed to 32-bit ARM since the core speeds are typically higher and the chips are more likely to have AES-NI.
