CopperSpice is a set of cross-platform C++ libraries (Core, Gui, Network, Multimedia, SQL, OpenGL, Vulkan, WebKit, XML, and more) derived from Qt and rewritten with modern C++20, including template-based reflection that removes the need for a meta-object compiler. It is LGPL-licensed and designed to be linked into any standard C++ application built with CMake.
Use cases
- build cross-platform desktop GUI applications in C++
- find a modern open-source alternative to Qt for C++
- add networking, SQL, or multimedia to a C++ app without Qt licensing
- use C++20 reflection-based signals and slots instead of moc
- develop widgets-based desktop apps with CMake and Ninja
- render SVG, OpenGL, or Vulkan content in a C++ application
When to choose
- you want a Qt-derived GUI library with no proprietary licensing constraints
- your codebase targets C++20 and you prefer template-based metadata over moc code generation
- you need a modular set of libraries (core, gui, network, multimedia, sql) you can link selectively
- you build with CMake and want prebuilt binaries or source builds across Linux, macOS, and Windows
When to avoid
- you need the full Qt ecosystem, Qt Quick/QML, or Qt tooling like Qt Designer
- your project must support compilers older than C++20
- you rely on third-party Qt add-ons or the large Qt community and package ecosystem
- you need a permissive license - CopperSpice is LGPL v2.1
