MicroUI is a compact immediate-mode UI library written in ANSI C, requiring no external dependencies and no specific rendering backend. It generates a per-frame command list that the host application submits to any renderer it chooses. Ideal for debug overlays, tool UIs, and embedded or resource-constrained environments where heavier frameworks are impractical.
