Spatius and LiveAvatar both target live, customer-facing avatar experiences. Their clearest difference is the delivery architecture: Spatius sends motion data for AvatarKit to render on the client, while LiveAvatar provides a managed cloud avatar pipeline.
Compare the decision areas.
Metrics use the current published framing. Test both products under the same session, client, and network conditions.
| Decision area | Spatius | LiveAvatar |
|---|---|---|
| Product role | Real-time avatar interaction layer | Managed live-avatar product |
| Rendering | AvatarKit on the client | Cloud-rendered media |
| AI stack | Customer owns the surrounding application | Managed avatar pipeline |
| Client framing | Web, iOS, and Android | Verify current LiveAvatar client options |
| Published network path | 10–20 KB/s / around 100 kbps | WebRTC media stream |
| Published cost framing | About 95% lower cost per minute | Credit or per-minute cloud model |

What sits behind the avatar?
The important distinction is what moves across the network and which parts of the AI product your team owns.
Customer-owned AI, client-rendered avatar
Spatius receives avatar speech audio and produces motion data. AvatarKit renders on the client. Your application owns ASR, LLM, TTS, tools, knowledge, CRM, scoring, workflows, and turn-taking.
Managed cloud avatar
LiveAvatar centralizes more of the visual pipeline. That can reduce assembly work, but the media path, session model, customization, and current plan become part of the platform decision.
Choose for the product you are building.
A fair comparison identifies where both products fit—and where they do not.
Choose Spatius when…
- Need a composable visual layer
- Own the agent and business logic
- Mobile and web delivery
- Bandwidth-sensitive products
Choose LiveAvatar when…
- Prefer a managed cloud avatar
- Already use the HeyGen ecosystem
- Web-first customer experience
- Want the vendor to own more output
Not the best fit
Spatius is not a complete agent platform. LiveAvatar may be less aligned when the product specifically requires lightweight motion data and local rendering.
Run a controlled proof of concept.
Do not compare two vendor demos with different inputs. Use one test plan and document what each platform includes.
- Use the same TTS audio and conversation script.
- Separate ASR, LLM, TTS, and avatar-layer latency.
- Measure full-session network traffic and recovery behavior.
- Compare equivalent pricing units and included services.
