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 Project is an open source collaborative effort hosted by the Linux Foundation to build scalable real-time operating system optimised for resource constrained devices (e.g. embedded systems) across multiple architectures [1]. The project's goal is to establish a neutral project where anyone can contribute technology to reduce the cost and time to market for the billions of IoT devices [2].
