Real-time API infrastructure that turns an audio stream into a synchronized 3D talking avatar.
Spatius is developer infrastructure for real-time AI avatars rather than a consumer app. It takes an audio stream over WebRTC or WebSockets, through a built-in LiveKit integration, and renders a synchronized 3D facial animation using a cloud-edge hybrid setup designed to run in 1080p at 25 frames per second on ordinary phones, monitors, or laptops without a dedicated GPU. Pricing is usage-based at roughly 0.007 USD per minute on its Scale plan, which the company positions against cloud-streaming alternatives it says typically cost far more per minute. The operator is Spatialwalk Pte. Ltd., a company registered in Singapore, founded in 2025.
Usage-based pricing starts around 0.007 USD per minute, about 0.42 USD per hour, on the Scale plan; there is no flat monthly subscription tier.
Use tool ↗Spatius is infrastructure for developers building avatar experiences, not a tool an end user would sign up for directly. Its edge-rendering pitch, running on ordinary devices without a dedicated GPU, targets a real cost problem in streaming digital humans. As a young, narrowly-scoped infrastructure company, it is best evaluated on a technical trial rather than the marketing claims alone.
