VoiceGateway is what we wish we had.
The open-source profiler for voice agents. Add one line and every STT, LLM, and TTS call is priced and timed. Works with LiveKit and Pipecat. An open-source MIT engine you can self-host, plus a hosted cloud at dash.voicegateway.dev. Bring your own provider keys: you keep them, we store the telemetry rows and never touch your audio.
An MIT engine, a hosted cloud, a dashboard. Cost rows and latency waterfalls for every STT, LLM, and TTS call, plus invoice reconciliation.
In your provider keys or your call audio. You run agents on your own credentials. We only store one telemetry row per request.
Principles
BYO keys, always
Your API keys stay on your servers. VoiceGateway sits beside your agent, not between your agent and the provider.
Open source at the core
The engine is MIT-licensed. Self-host the full stack, or use the hosted cloud when you would rather not operate it yourself.
Telemetry, not audio
We record per-request cost and latency metadata. Your conversations never leave your infrastructure.
