Several versions of the OpenGL ES specification now exist. Vulkan, a next-generation API from Khronos, is made for simpler high performance drivers for mobile and desktop devices. OpenGL ES is managed by the non-profit technology consortium Khronos Group. The GLU library and the original GLUT are not available for OpenGL ES, freeglut however, supports it. The API is cross-language and multi-platform. OpenGL ES is the "most widely deployed 3D graphics API in history". It is designed for embedded systems like smartphones, tablet computers, video game consoles and PDAs.

OpenGL for Embedded Systems ( OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU).
