NuttX Alternatives

NuttX is described as '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' and is an app. There are four alternatives to NuttX for Windows, Linux, Mac and BSD. The best NuttX alternative is FreeRTOS, which is both free and Open Source. Other great apps like NuttX are Zephyr, RIOT and embOs.
