C++Builder vs Qt Creator

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.

Qt Creator is an IDE for making applications for desktop, embedded, and mobile systems, as well as web browsers. It supports work from project setup and interface design through coding, building, deployment, running, and debugging. The editor offers semantic highlighting, syntax checks, code completion, search, and refactoring. It understands C++ and QML, with some Python language services when a language server is available. Build integrations cover CMake, qmake, Qbs, and Autotools; generic projects can use configurable build commands. Integrated debuggers and analysis tools can help investigate memory leaks, profile execution, and analyze CPU use. Testing support includes Boost.Test, Catch2, Google Test, Qt Quick Test, Qt Test, and CTest. Qt Creator supports AI agents; its documentation lists GitHub Copilot and an MCP Server extension. An open-source version is available at free, subject to LGPL/GPL obligations for Qt framework use. Qt’s commercial evaluation lasts 10 days and is for evaluation, not production or product development. Commercial use requires an active license for each developer, and Qt-based device distribution may also need licenses.
