# VRChat

**APIs profiled:** 2

VRChat is a social virtual-reality platform where users create avatars and worlds in Unity with the first-party VRChat SDK (Worlds, Avatars, Udon and UdonSharp), publish them through the VRChat Package Manager, and meet inside a persistent multi-user universe playable on PC VR, standalone headsets and desktop. VRChat operates a live web API at api.vrchat.cloud that powers its own client and website, but it explicitly does not document, version, or support that API for public use: its Creator Guidelines state endpoints may be added, removed, or changed with no warning. The machine-readable surface VRChat does publish is the creator toolchain — the VPM package listings at packages.vrchat.com, the vpm CLI on NuGet, the OSC and OSCQuery interfaces for external avatar and input control, an llms.txt documentation index, and a public Statuspage.
