Show HN: Voice and Messaging Agents Using the WhatsApp Calling API

A few months ago, WhatsApp released a calling API. I’d been experimenting with conversational interfaces for a while, and it seemed like a good chance to build something that could let businesses create voice-based agents without much setup.

I’ve been working on this over the past few months, and the beta is now publicly available. The idea is simple: you point the platform to your website URL, and it automatically configures a voice + messaging agent that customers can call or message. No code required.

My expectation is that many businesses will eventually offer some form of conversational interface by default, and I wanted to see whether a tool that simplifies that process could be useful. I’d appreciate feedback—especially around rough edges, missing features, or anything that seems confusing.

You can try it out directly in the browser, with a minimal barrier to testing. No long onboarding flows.

Happy to answer questions or go into technical details in the thread. Thanks!
