Show HN: Whispey – Open-source observability for LiveKit voice agents

2 points

10 months ago

We run multiple voice AI agents on LiveKit and kept running into the same headaches: * No way to see TTFT (time to first token) per call * Hard to measure cost per call * No visibility into latency across STT → LLM → TTS * Debugging was basically guesswork

So we built Whispey to solve it.

What it does: * Cost analytics * Latency breakdowns (VAD → STT → LLM → TTS) * Agent evaluation metrics * Campaign tracking * Downloadable recordings + transcripts

Runs on Vercel + Supabase today, AWS-native version is coming. It’s tightly integrated with LiveKit.

If you’ve built voice agents on LiveKit, we’d love for you to try it out and share what’s been working for you. Always looking for best practices from other builders.
