The Zephyr Project is a Linux Foundation hosted Collaboration Project. It’s an open source collaborative effort uniting developers and users in building a best-in-class small, scalable, real-time operating system (RTOS) optimized for resource-constrained devices, across multiple architectures.

The Zephyr Project is a neutral project where silicon vendors, OEMs, ODMs, ISVs, and OSVs can contribute technology to reduce costs and accelerate time to market for billions of connected embedded devices. The software is a perfect choice for simple connected sensors, LED wearables, modems, and small wireless gateways.

As an open source project, the community evolves the project to support new hardware, developer tools, sensors, and device drivers. Improvements are frequently delivered to incorporate enhancements in security, device management capabilities, connectivity stacks, and file systems.
