In their own words
Arm Keil MDK
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.
C++Builder
C++Builder is an integrated C++ development environment for building native applications, with Windows development emphasized. Its compiler has initial support for C++23 and pairs Clang enhancements with the Dinkumware STL. The VCL component library provides visual and non-visual elements for Windows interfaces, and build configurations can use MSBuild or CMake. FireDAC connects natively to Oracle, SQL Server, MySQL, SQLite, PostgreSQL, DB2, and Firebird. HTTP and REST client libraries can invoke REST services, with components for AWS and Azure also included. The IDE names Subversion and Git as supported repository integrations, and plugins can add tool windows, code completion, syntax highlighting, and debugging hooks. Integrated debugging and testing tools are listed. Community Edition costs nothing for limited commercial use, while annual revenue remains under US$5,000 and the team has no more than five developers. A 30-day free trial is available. Enterprise Edition includes an InterBase ToGo license for encrypted embedded database capabilities.
