kiero

Kiero is a lightweight and flexible hooking library designed to intercept graphics API functions, especially for injecting custom code into DirectX (9, 11, 12) and OpenGL-based applications. It’s often used for overlay rendering, game modifications, debugging, or reverse engineering purposes. By providing an easy-to-use interface for binding and overriding rendering calls, Kiero enables developers to create tools like custom HUDs, frame analyzers, or graphical overlays across a wide variety of games and applications.
