Ultra App Kit

Built to power a new generation of game development tools, Ultra App Kit provides an easy-to-use C++ programming SDK for creating cross-platform desktop GUI applications. Learn from extensive documentation with hundreds of examples. Integrate a 3D engine or OpenGL rendering for embedded 3D graphics. Make it Snappy Unlike other alternatives like ImGui, Ultra App Kit draws using retained mode instead of immediate mode . This makes resizing windows and interacting with screen elements fast and responsive, even with the most complex interfaces. Pixel-Perfect Pixels on any Screen DPI scaling is baked into the core of our design, for a beautiful clean appearance at any resolution. Small and Efficient Ultra App Kit runs with no extra dependencies and produces tiny executables (usually less than one megabyte after UPX compression) that start up and exit instantly. Code Once, Compile Everywhere Ultra App Kit now supports Windows, Linux, and macOS, so you can build beautiful applications that run everywhere and include native support for Apple Silicon.
