    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'. There are three alternatives to NuttX for Linux, Mac, Windows and BSD. The best alternative is FreeRTOS, which is both free and Open Source. Other great apps like NuttX are Zephyr (Free, Open Source) and RIOT (Free, Open Source).
