RT-Thread Description
RT-Thread, short for Real Time-Thread, is an embedded real-time multi-threaded operating system. It has been designed to support multi-tasking, allowing multiple tasks to run simultaneously. Although a processor core can only run one task at a time, RT-Thread executes every task quickly and switches between them rapidly according to priority, creating the illusion of simultaneous task execution.
RT-Thread is mainly written in the C programming language, making it easy to understand and port. It applies object-oriented programming methods to real-time system design, resulting in elegant, structured, modular, and highly customizable code.
The system comes in a few varieties. The NANO version is a minimal kernel that requires only 3KB of flash and 1.2KB of RAM. For resource-rich IoT devices, RT-Thread can use an online software package management tool, together with system configuration tools, to achieve an intuitive and rapid modular design.

FreeRTOS
FreeRTOS, which was developed in partnership with some of the world's most renowned chip companies over a 15 year period, is now downloaded every 170 second. It is a market-leading real time operating system (RTOS), for microcontrollers, small microprocessors. FreeRTOS is freely distributed under the MIT open-source license. It includes a kernel as well as a growing number of IoT libraries that can be used across all industries. FreeRTOS is designed with reliability and ease-of-use in mind. The FreeRTOS kernel has been trusted by leading companies around the world as the standard for microcontrollers/small microprocessors. It is known for its reliability, small footprint, and wide device support. You don't need to know how to set up a project. There are pre-configured demos that can be used as templates and IoT reference integrations. You can quickly download, compile, then get to market quicker. Our partner ecosystem offers a variety of options, including professional support and community contributions.

OpenWrt
OpenWrt is an extensible GNU/Linux distribution that can be used on embedded devices (mostly wireless routers). OpenWrt, unlike other router distributions, is a fully-featured and easily modifiable operating systems for embedded devices. This means that you can have all of the features you want with no bloat thanks to a modern Linux kernel. OpenWrt allows you to create a single static firmware instead of trying to create one. It also provides an optional filesystem that can be writable with package management. This allows you to bypass vendor restrictions on application selection and configuration and allows you to use packages for customizing embedded devices to suit any application. OpenWrt is a framework for developers to build applications without the need to create a full firmware image and distribute it.

Zephyr
From simple embedded environmental sensors to advanced embedded controllers and smart watches to IoT wireless applications, there are many options. Implements configurable architecture-specific stack-overflow protection, kernel object and device driver permission tracking, and thread isolation with thread-level memory protection on x86, ARC, and ARM architectures, userspace, and memory domains. Supports combining application-specific code and a custom kernel on platforms without MMU/MPU or memory constrained devices to create a monolithic images that are loaded and executed on a system’s hardware. Both the kernel and application code are executed in a single address space.
