Unity is a game engine, IDE and service suite developed by Unity Technologies. As of 2016 it is the most widely-used game development system.

It targets mobiles, desktops, consoles, web browsers, and VR devices. Unity is used for 3D, 2D and VR/AR. Cloud services include advertising, in-app purchase, and cloud building. The Unity application itself is for both Windows and macOS.

In Unity, components are written in C# and are usually compiled using Mono or IL2CPP.

Major subsystems include PhysX game physics, Mecanim animation, a third-party asset store, and Unity.UI.
