The decision in context

LiveKit is positioned as realtime agent infrastructure for teams that own the application and model stack. Rime is positioned as conversational TTS with separate models and enterprise deployment options. Start by deciding who owns the missing layers, then inspect the documented differences below.

Developer Frameworks and Voice Engines are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.

8 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.
