MicroUI – A tiny, portable, immediate-mode UI library written in ANSI C

MicroUI is a lightweight, immediate-mode UI library written in ANSI C with around 1,100 lines of code that operates within fixed memory and includes built-in controls like windows, buttons, sliders, and text boxes. It works with any rendering system capable of drawing rectangles and text, while remaining portable and easily extensible for custom controls. The library is released under the MIT license and is designed as a minimal foundation rather than a feature-rich framework.
