FreeRTOS is described as 'Real-time operating system kernel for embedded devices that has been ported to 35 microcontrollers. It is distributed under the MIT License' and is an app in the development category. There are four alternatives to FreeRTOS for Windows, BSD, Mac and Linux. The best FreeRTOS alternative is Zephyr, which is both free and Open Source. Other great apps like FreeRTOS are NuttX, embOs and RIOT.
Zephyr is a small real-time operating system for connected, resource-constrained devices supporting multiple architectures and released under the Apache License 2.0 backed by the Linux Foundation.
Zephyr is the most popular Windows, Mac & Linux alternative to FreeRTOS.
Zephyr is the most popular Open Source & free alternative to FreeRTOS.
NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards.
embedded Operating System (embOS), is a Real-time operating system, developed by the Company SEGGER Microcontroller. It's designed to be used as a foundation for the development of embedded real-time applications for a wide range of µc.
RIOT is a small operating system for networked, memory-constrained systems with a focus on low-power wireless Internet of things (IoT) devices. - Wikipedia
