What three.ws Avatar SDK is
three.ws Avatar SDK provides app developers with web components, React bindings, an iframe avatar creator and cloud upload for 3D avatars. Its lightweight viewer renders GLB or GLTF models with Three.js and OrbitControls, without AI or WebSocket features. A separate agent-3d component provides chat, voice, lipsync, animation and skills. The SDK includes typed, tree-shakeable React 18+ bindings and a useAvatar hook; React is optional when installing it with Three.js. AvatarCreator opens Avatar Studio or Selfie Studio in an iframe and returns an exported GLB Blob. The saveBlob function uploads a GLB to R2 and registers the avatar; the SDK also supports USDZ generation for iOS and a half-body variant for VR. It bundles more than 50 Mixamo animations and supports Mixamo-compatible rigs. The maker describes the SDK as self-hostable open source under Apache-2.0. Uploads through saveBlob require a bearer token with the avatars:write scope, and avatar visibility can be public, unlisted or private. The Free plan includes one agent and one custom avatar; Pro costs $49 a month and includes unlimited agents and custom avatars, among other features.
