The PlayStation 3 uses the XrossMediaBar (XMB) as its graphical user interface, which is also used in the PlayStation Portable (PSP) handheld console, a variety of Sony BRAVIA HDTVs, Blu-ray disc players and many more Sony products. Due to the fact that it requires a licensing agreement with Sony (which is considered expensive), a number of open source and homebrew PS3 SDKs are available in addition to a number of leaked PS3 SDKs. Unlike the Software Development Kit (SDK) for mobile apps, Sony's PlayStation 3 SDK is only available to registered game development companies and contains software tools and an integrated hardware component. This is similar to the later PlayStation 4 console which also has two APIs, the low level GNM and the higher level GNMX. LibGCM is a low level API, and PSGL is a higher level API, but most developers preferred to use libGCM due to higher levels of performance.

The 3D computer graphics API software used in the PlayStation 3 is LibGCM and PSGL, based on OpenGL ES and Nvidia's Cg.
