What is libui?
libui is a portable GUI library written in C that enables developers to create native desktop applications for Windows, Unix (using GTK+), and macOS. It provides a unified API that abstracts each platform's underlying GUI toolkit, allowing applications to maintain a native look and feel without platform-specific code.
