## The Hook

Unmute lets you define a voice agent once and compile the same spec onto the runtime you actually ship.

## What's Good

MIT (slng-ai/unmute). Single voice-agent definition with targets for LiveKit, Pipecat, and SLNG, plus docs for tools, orchestration, telephony, tracing, and transfers at unmute.ai. ★~15 — the portable voice-agent spec wedge, not another locked runtime demo.

## The Catch

Vs Voicebox (local TTS/STT studio) and raw LiveKit/Pipecat apps: Unmute is the compile-from-spec layer, not the voice models and not a single runtime. Young project; you still operate the chosen target stack and vendor credentials behind the compile.

## Verdict

MIT voice-agent spec compiler. Write once when you refuse to rewrite the agent for each voice runtime.
