Built to power a new generation of game development tools, Ultra App Kit provides an easy-to-use C++ programming SDK for creating desktop GUI applications.
Unlike other alternatives, Ultra App Kit uses retained mode rendering with system-level drawing commands. This makes resizing windows and interacting with screen elements fast and responsive, even with the most complex interfaces.
DPI scaling is baked into the core of our design, for a beautiful clean appearance on any screen.
Ultra App Kit 1.1 is now available on our website and on Steam. This free update brings cross-platform development to our fast resolution-independent GUI toolkit. In addition to Windows, Mac and Linux are now supported, which means you can code once and compile everywhere to easily create cross-platform GUI applications.
Builds on Linux use minimal dependencies and will work on virtually any distro without any additional libraries to install. This effectively solves the Linux user interface problem forever and provides us with a strong foundation on which to build new game development tools that look great and run everywhere.
Ultra App Kit is gorgeous on macOS and works with both Intel-based Macs or running natively on Apple Silicon.
Along with various small bug fixes, version 1.1 adds the following new commands:
You can get the standalone version now for just $1.99 a month, or get a Steam key for $19.99. Both versions will give you support to build GUI applications for Windows, Linux, and Mac.
