three.ws Avatar SDK
What it is
three.ws Avatar SDK gives app developers components and workflows for adding 3D avatars to web projects. It includes web components, React bindings, an iframe avatar creator, and cloud upload. The lightweight three-ws-viewer renders GLB or GLTF models with Three.js and OrbitControls, without AI or WebSocket features; the separate agent-3d component provides chat, voice, lipsync, animation, and skills. React support includes typed, tree-shakeable bindings for React 18+ and a useAvatar hook, while React remains optional alongside Three.js. AvatarCreator opens Avatar Studio or Selfie Studio in an iframe and returns an exported GLB Blob. The saveBlob function uploads GLB files to R2 and registers the avatar; the SDK also supports USDZ generation for iOS and a half-body VR variant. It bundles more than 50 Mixamo animations and supports Mixamo-compatible rigs. The SDK is described as self-hostable open source under Apache-2.0. Uploading through saveBlob requires a bearer token with the avatars:write scope. The Free plan costs nothing, billed forever, and includes one agent, one custom avatar, unlimited embeds, a default rig, 200 animation clips, and community support.
