The decision in context

Cognigy is positioned as enterprise agent workflows and Voice Gateway for existing contact-center environments. LiveKit is positioned as realtime agent infrastructure for teams that own the application and model stack. Start by deciding who owns the missing layers, then inspect the documented differences below.

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

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

Both records have documented values for Product type, Technical setup, Pricing model, ElevenLabs TTS, Deepgram STT, OpenAI models, Anthropic models, Google models, Bring your model, MCP tools, Function / tool calling, Interruption controls and additional fields shown in Compare. Matching availability does not measure behavior under your call conditions.
