ProductIntroducing Streamoji Avatars SDK: Build Real-Time 3D Avatar Experiences on the Web
TL;DR
An avatar SDK is how you ship 3D characters in a product instead of a one-off renderer. Users expect real-time, human-like engagement — and that is what a 3D avatar SDK like Streamoji is built to do.
Stop treating avatars as visual assets. Start treating them as live, interactive digital entities.
Whether you're building SaaS, virtual meetings, or AI assistants, Streamoji provides the infrastructure to integrate real-time 3D avatars with minimal effort.
What is an avatar SDK?
A 3D avatar SDK packages creation, rigging, rendering, and live facial animation so you are not stitching photo-to-mesh, blendshapes, and WebRTC yourself. Streamoji's avatar SDK targets web and realtime apps: selfie avatars, expression streaming at ~40 kbps, and drop-in SDKs for React, Unity, and Unreal.
