Introducing Streamoji Avatars SDK: Build Real-Time 3D Avatar Experiences on the Web
March 22, 2026 by Streamoji Team
As digital experiences evolve, users no longer want static interfaces or passive interactions. They expect real-time communication, human-like engagement, and immersive environments.
This is exactly where Streamoji Avatars SDK comes in.
Streamoji is redefining how developers build avatar-driven applications by offering a powerful, scalable, and real-time avatar infrastructure that works directly on the web. Instead of treating avatars as visual assets, Streamoji transforms them into live, interactive digital entities.
Whether you're building a SaaS product, a virtual meeting platform, or an AI assistant, Streamoji provides the tools to integrate real-time 3D avatars with minimal effort.
What is Streamoji Avatars SDK?
The Streamoji Avatars SDK is a developer toolkit designed to help you create, render, and stream real-time facial expressions for interactive apps.
