Immediate-Mode GUI Libraries

Nuklear is a minimal, header-only graphical user interface toolkit written in C. It utilizes an immediate-mode rendering model, where the interface is reconstructed and drawn directly within the application loop each frame. This approach eliminates the need for persistent widget state or complex synchronization between the interface and underlying application data. The library is designed for portability and integration into resource-constrained environments. It requires the host application to manage memory manually, allowing it to function in systems that lack standard library support. By d
