Arm Keil MDK vs QNX Software Development Platform

Arm Keil MDK is a toolchain for embedded software targeting Cortex-M and Ethos-U processors. MDK v6 supports command-line, IDE, and continuous-integration workflows across major operating systems. It includes Keil Studio extensions for Visual Studio Code, Keil μVision, Arm Compiler for Embedded, and Arm Fixed Virtual Platform models. Software packs add device and board support, middleware, components, code templates, and example projects independently of the toolchain. Keil Studio supports CMSIS workflows with an integrated debugger and extensions for creating, building, and testing embedded applications. Listed integrations include CMSIS-FreeRTOS, Keil RTX5, MDK-Middleware, IoT clients, CMSIS-DAP, ULink, and third-party debug adapters. Community is for non-commercial use. The listed MDK v6 Essential plan costs $99 a month per license; Professional costs $199 a month per license and adds Arm Virtual Hardware, functional-safety compiler tools, and legacy tools including Arm Compiler 5. Keil μVision is available only for Windows hosts.

QNX Software Development Platform 8.0 is a development environment for mission-critical and safety-critical embedded systems. Its components include QNX OS 8.0, the QNX Tool Suite, QNX Software Center, and Board Support Packages. The OS is fully pre-emptive, with strict timing constraints and guaranteed response times, and is described as near-linearly scalable across systems-on-chip with 2 to 64 CPU cores. Target architectures are Armv8, Armv9, and x86-64. Development tools include the Eclipse-based QNX Momentics IDE, a Visual Studio Code toolkit, and command-line profiling and debugging tools; the listed build options include the QNX system builder and command-line build tools. Security features include secure boot, QNX Trusted Disk, Pathtrust, ASLR, OpenSSL 3, and FIPS 140-2 crypto libraries. QNX Accelerate provides access to cloud hardware targets running QNX technology. Windows, Linux, and macOS are listed as host platforms. A free non-commercial license and a 30-day commercial evaluation are available. Commercial development requires a commercial license, and shipping a product requires a separate distribution license; pricing is on request.
