Show HN: I Created a UptimeRobot for AI Voice Agents

Hi HN, recently I spent quite some time building phone-based AI voice agents. Before every customer meeting, I found myself calling the AI agent to verify it was still "alive". I have some friends working in the call-center/voice-agent space and they told me they had the same issues. So I decided to build a tool to monitor my AI agents. And since I have the problem and my friends have it, I thought why not build a tool everyone can use.

I would really appreciate any feedback! It works pretty well, but I still have to make it more robust. Also, I have no idea yet how to best monetize it. If I get some traction/encouraging feedback, I'll add feature tests (e.g., can you still make a reservation, can the agent deal with noise, etc.).

The UX is heavily inspired by https://uptimerobot.com/ and https://supabase.com/

Here is some behind the scenes on I coded that in only one week: https://www.callgeist.com/about

PS: Part of this project is to showcase my work, as I'm currently looking for new opportunities (please see my HN profile.
