powered by THREADX RTOS

The Industrial Grade solution for deeply embedded IoT devices based on THREADX RTOS, FILEX embedded file system, GUIX embedded GUI, NETX and NETX DUO embedded TCP/IP, and USBX embedded USB. Proprietary, fully supported, containing absolutely no open source. At the heart of the X-WARE IoT PLATFORM is the embedded industry's most deployed THREADX Real-time Operating System (RTOS), with well over billion deployments – and counting.


X-WARE IoT PLATFORM solutions serve all major embedded IoT markets, and are offered with full source code and no run-time royalties.

is Industrial Grade

We believe in making embedded IoT development as easy as possible. Our IoT solutions are the smallest, fastest, safest, most advanced, and secure available. That's why we call them Industrial Grade. With our Industrial Grade IoT solutions and industry-leading commitment to support, we make embedded IoT development as easy as it gets.
With a minimal footprint of 2KB, THREADX enables your designs to fit in the most memory-constrained IoT devices. That leaves more memory for you to achieve your functionality goals, or to reduce the memory cost of your device. For example, the X-WARE IoT PLATFORM enables cloud connectivity in as little as 25KB!
Let's make things small!
We provide the most field-proven IoT solution with over billion deployments of THREADX worldwide. Additionally, we provide one of the most pre-certified RTOS solutions – allowing you to focus solely on your application certification. Our pre-certifications include IEC 61508 SIL 4, IEC 62304 Class C, and ISO 26262 ASIL D. THREADX has also been DO-178 certified.
Let's make things safe!
We provide an EAL4+ Common Criteria security certified environment, including full IP layer security via IPsec and socket layer security via TLS and DTLS. Our software crypto library has achieved FIPS 140-2 certification. We also leverage hardware cryptographic capabilities, memory protection via THREADX MODULES, and support for ARM's TrustZone ARMv8-M security features.
Let's make things secure!
We provide advanced technology in all of our products, including the unique preemption-threshold technology found in THREADX. Preemption-threshold improves device responsiveness, while at the same time reducing unnecessary overhead. Event chaining, full determinism, and THREADX Modules are more examples of our advanced technology.
Let's make things advanced!
We provide the fastest run-time environment, boasting sub-microsecond context switching in THREADX, and near-wire-speed network performance in NETX DUO. Not only fast, our solutions are highly deterministic – they perform in a fast, predictable manner regardless of system load.
Let's make things fast!
We provide the most intuitive APIs and industry-leading documentation. All of our solutions are proprietary – no open source – and all share the same look and feel. In addition, our solutions automatically scale and are designed for run-time adaptation rather than rigid compile time limits.
Let's make things easy!

We have followed the growth trajectory of THREADX in the wireless and IoT markets since the company’s founding, and are increasingly impressed by the widespread industry adoption of THREADX.
