Zephyr Project

The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M, Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of supported boards.

Getting Started

Welcome to Zephyr! See the Introduction to Zephyr for a high-level overview, and the documentation's Getting Started Guide to start developing.

Community Support

Community support is provided via mailing lists and Discord; see the Resources below for details.
