hey there 👉👈
this is my second launch of an open source product here on product hunt. and this time it’s in voice agents. 🗣️
@oliver_wb and I were both voice agent developers at PlayHT – and, in order to find bugs in our agents, we would spend countless hours manually calling them and listening to conversation recordings.
so, we’ve decided to build an open-source platform that does this automatically.
how does it work? 🤔
1. run tests 📝
our voice agents will call your voice agents to test them out. you can run tests via github actions, API call, or directly in the UI. pinpoint exactly where errors occur in the audio along with an analysis of what occurred.
2. monitor production calls 📞
we help you identify latency, interruptions, and correctness of your calls in real-time. set up slack alerts for calls where latency goes above a certain amount or when the agent fails to collect the user’s email address, etc.
