About the Zephyr Project

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. Because Zephyr is modular and supports multiple architectures, developers can create a solution that meets their needs.

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.

The Zephyr® Project strives to deliver the best-in-class RTOS for connected resource-constrained devices, built to be secure and safe.

Why create another RTOS?

Change is happening fast in the connected devices space, and the technical requirements are vast. No one person or company has all the answers. Collaboration is key to driving down costs and accelerating time to market. A platform to facilitate collaboration must be commercially neutral, inclusive of all contributors, and governed such that all interests are fairly represented.

That’s why the Zephyr Project was created. We’re using an open, collaborative environment to deliver an RTOS that’s open source, applicable in a wide diversity of use cases, and currently supports more than 170 hardware devices, more than any other RTOS, while giving members a clear path for upstreaming code and participating in the future roadmap.

Engage with our community. We’re happy to answer your questions and share how becoming a member of the Zephyr Project was the right choice.
