Hey Product Hunt 👋 I'm Elvarin — creator of BXP. I built this because I kept asking the same question: why does every air quality device, app, and government system use a completely different data format? Why can a sensor in one city not speak to a hospital in another? The answer was that nobody had built the standard yet. BXP is that standard. Pure software — like HTTP for the web. No hardware required. Any phone, any existing sensor app, any government data feed, any community report can write BXP-formatted data immediately. The v2.0 specification is complete, live on GitHub, and Apache 2.0 licensed. Forever free. I am actively looking for: → Developers to build reference implementations → Researchers to validate the agent schema → Organizations interested in adoption → Anyone who wants to help build what the world needs Full spec: github.com/bxpprotocol/bxp-spec Happy to answer any questions about the protocol, the design decisions, or where this goes next. The air is public. The data should be too.
