    SerenityOS

    SerenityOS

    The Serenity Operating System

    SerenityOS is an open source Unix-like operating system project with its own custom kernel, graphical user interface, system libraries, and userland tools. It combines a nostalgic “90s UI aesthetic” with modern system capabilities: a preemptive, multi-threaded kernel, own browsers, network stack, file systems, IPC, security features, and a suite of graphical / developer applications. The project is both a hobbyist OS and a polished engineering sandbox.

    StateOS

    StateOS

    Free real-time operating system (RTOS) for microcontrollers

    StateOS is a compact, open-source real-time operating system designed for embedded systems and written in ANSI C. It supports cooperative and preemptive multitasking, making it ideal for running multiple real-time tasks on microcontrollers. StateOS emphasizes clarity and ease of integration with existing projects and provides a full set of synchronization primitives, timers, and message-passing tools. It's widely used in industrial and academic settings for prototyping and low-level firmware development.

    QP Real-Time Event Frameworks & Tools

    QP Real-Time Event Frameworks & Tools

    Real-Time Event Frameworks based on active objects & state machines

    ...The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows.

    StateOS

    StateOS

    Free real-time operating system designed for microcontrollers

    Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M, STM8. It was inspired by the concept of a state machine. Procedure executed by the task (task state) doesn't have to be noreturn-type. It will be executed into an infinite loop. There's a dedicated function for immediate change the task state.
