lucasdietrich/AVRTOS

AVRTOS is a classic 'educational' or 'sandbox' project. While technically competent—offering features like preemptive scheduling, semaphores, and mutexes on resource-constrained 8-bit hardware—it lacks a viable path to enterprise or widespread industrial adoption. With only 45 stars over 5 years and zero recent velocity, it remains a personal experiment rather than a living ecosystem. In the professional embedded space, developers needing an RTOS for AVR typically gravitate toward FreeRTOS (the industry standard with massive vendor support) or avoid an RTOS entirely due to the extreme RAM constraints of 8-bit chips (where a 2KB RAM budget makes task stacks prohibitively expensive). The 'Zephyr-inspired' API is a nice touch for developers familiar with modern RTOS patterns, but it doesn't create a moat against established players. Frontier labs have zero interest in 8-bit RTOS development, and platform risk is low only because the project resides in a niche that is already 'solved' by existing open-source and proprietary tools. It is functionally displaced by any project with active maintenance and a hardware abstraction layer (HAL) that supports more than one architecture.
