What three.ws Avatar SDK is
three.ws Avatar SDK gives app developers tools to add 3D avatars through web components, React bindings, an embedded creator, and cloud upload. Its three-ws-viewer displays GLB and GLTF models with Three.js and OrbitControls; this viewer does not include AI or WebSocket features. The separate agent-3d component provides chat, voice, lipsync, animation, and skills. Developers can use typed, tree-shakeable React 18+ bindings and a useAvatar hook, or install the SDK without React. AvatarCreator opens Avatar Studio or Selfie Studio in an iframe and returns a GLB Blob. The saveBlob function uploads GLB files to R2 and registers avatars, with USDZ generation for iOS and a half-body variant for VR. The SDK includes more than 50 Mixamo animations and supports compatible rigs. It is described as self-hostable open source under Apache-2.0. Uploads require a bearer token with the avatars:write scope, and avatar visibility can be public, unlisted, or private. The Free plan costs nothing, billed forever; Pro costs $49 a month, billed monthly.
