Best IoT Operating Systems

Compare the Top IoT Operating Systems as of April 2026

What are IoT Operating Systems?

IoT operating systems (OS) are specialized software platforms designed to run on Internet of Things (IoT) devices, providing the necessary functionality for resource management, communication, and real-time processing. These operating systems are optimized for low power consumption, small memory footprints, and efficient processing, allowing IoT devices to operate in environments with limited resources. IoT operating systems typically offer features like device control, sensor management, connectivity protocols, and security to ensure that IoT devices perform reliably and securely. They are used in a variety of IoT applications, such as smart home devices, wearables, industrial machinery, and automotive systems. Compare and read user reviews of the best IoT Operating Systems currently available using the table below. This list is updated regularly.

    Torizon

    Torizon

    Toradex

    Torizon makes developers more productive and helps them create easy-to-maintain products. Integrated over-the-air updates and device monitoring allow you to ship earlier, patch bugs in the field, deliver new features and detect issues faster. Software containerization simplifies maintenance and provides an additional layer of robustness. Torizon is constantly validated on Toradex System on Modules (SoMs) to ensure that you can fully focus on your application, rather than the operating system. Torizon lets you develop your product in an agile and iterative fashion. The seamlessly integrated remote update features make it possible to deploy new software easily, while device monitoring gives you instant feedback about performance and potential issues.

    LynxOS

    LynxOS

    Lynx Software Technologies

    LynxOS has been deployed in millions of embedded devices and has operated reliably for 30+ years across multiple safety and security-critical embedded markets. It is a tried and true approach for hosting applications on a Unix-like OS model wherein all resources and application services are centrally managed by a common kernel and is best-suited for working with hardware architectures that predate virtualization. We want our customers to buy what they need, and only what they need. Real-time operating systems can provide a tremendous amount of value, but they are not required for every embedded system design. For a more complete listing of our RTOS-related resources, visit our Embedded Systems Learning Center, which is filled with helpful material for making software purchase decisions as you design or update your system and consider which real-time platform vendor is right for you.

    MIPS Embedded OS (MEOS)
    We collaborate with open-source and commercial partners to provide MIPS support for many of the popular Real Time Operating Systems (RTOS) and the new generation of IoT specific Operating Systems. In addition, we have developed the MIPS Embedded Operating System (MEOS) with Virtualization extensions that targets deeply embedded applications and the IoT space. MEOS is MIPS’ in-house real-time operating system (RTOS). Being in-house, it is always the first to support new cores and architecture features. Version 3.1 of MEOS includes a virtualization library to extend MEOS into a hypervisor for use on MIPS cores which implement the MIPS Virtualization module. Where possible we will assist in the development open-source real-time/IoT operating systems through the donation of engineering resource or the supply of development hardware and tools.
