Voice agent frameworks and orchestrators compared

Turns already tells you which turn-detector is best. This page is what assembles the rest of the pipeline: transport (WebRTC, WebSocket, SIP/PSTN), tool-calling and multi-agent architecture, observability, and whether you self-host it or buy it as a managed platform.

Surveyed, not benchmarked. Nothing on this page was measured by OpenGauntlet's judge pipeline.

How to read this section

None of this is scored by the judge pipeline. OpenGauntlet measures Conversational Language Humanlikeness in text. This section is a sourced survey of orchestration frameworks and platforms, not a trial. Where a claim could not be verified against a primary source, it says so rather than smoothing it over.

Turn-taking behavior is covered elsewhere. Several tools here — Pipecat, LiveKit Agents, Rasa, Bolna — also appear on the Turns page with a row scoped ONLY to their turn-detection/interruption-handling behavior. This page covers everything else: transport, tool-calling, architecture, observability, deployment.

What we couldn't establish

A comparison that hides its gaps is less useful than one that names them.
