QNX is a real-time operating system and hypervisor for embedded systems, used in automobiles, medical devices, programmable logic controllers, automated manufacturing and trains. Its product family includes the QNX Software Development Platform, a microkernel RTOS for safety-critical devices, and development tools. QNX runs on the customer's own hardware and is not offered as a hosted cloud service.
QNX is a division of BlackBerry Limited and is headquartered in Ottawa, Canada. The software is proprietary, so customers depend on the vendor's licence terms, update channel and long-term support rather than on source code they can modify. Because it runs on devices that the customer builds or operates, the customer's system design determines where any data is processed. For European manufacturers, the main questions are the supplier's Canadian base and the availability of support and security updates over the product's lifetime.
