SAFERTOS® is based on the functional model of the FreeRTOS™ kernel, a market leading embedded RTOS with over 100,000 downloads per year.
However, SAFERTOS® is not the FreeRTOS™ kernel. It has been completely redesigned by our team of safety experts. Our engineers took the FreeRTOS™ kernel functional model, subjected it to a full HAZOP, identified all areas of weakness within the functional model and API, and generated a set of safety requirements. The resulting functional and safety requirements sets were put through an IEC 61508-3 SIL 3 development life cycle, the highest possible for a software only component, creating the SAFERTOS® code base and DAP.
Start Your Development for Free
As the FreeRTOS™ kernel and SAFERTOS® share the same functional model upgrading is easy. Many of our customers prototype using the FreeRTOS™ kernel, and convert to SAFERTOS® at the start of their formal development phase.
Our workshop demo, available to download for free, walks you through the upgrade process. It contains:
- An example FreeRTOS™ project;
- SAFERTOS® project;
- Detailed App Note to walk you through the exercise.

Our Relationship with FreeRTOS™
WHIS leverage RTOS technology from FreeRTOS.org, the market leading embedded real time operating system downloaded every 120 seconds on average in 2017.
Richard Barry created FreeRTOS™ while an employee at WHIS. WHIS engineers worked closely with Richard, providing a safety critical upgrade to FreeRTOS™, SAFERTOS®, and the flexible commercial licensing, training, and support that FreeRTOS™ users needed.
Free Manual
Included in our Download Centre is a manual detailing how to upgrade from FreeRTOS™ to SAFERTOS® in easy steps.
Why not use the FreeRTOS kernel?
The FreeRTOS™ kernel has been designed for maximum performance and minimum resource use, but lacks many of the features and checks identified during the HAZOP vital for safety critical applications.
Developing a safety critical RTOS is about more than just applying process to an existing code base. Risk management is required across the complete development life cycle to identify a full set of safety requirements. These safety requirements will have a major impact on the implementation of the RTOS, contribute significantly to the all-important safety manual and result in a trusted product containing the key features essential for safety critical use.
SAFERTOS® is pre-certified to IEC 61508-SIL 3, and supplied with a full Design Assurance Pack giving complete transparency over the full Design Life Cycle- saving you time and money whilst reducing your time to market.
