The goal of OpenVitals is to create a series of open-source devices that continuously collect and analyze data about the human body and its environment. By making these tools accessible and transparent, we aim to build a global ecosystem where developers, researchers, and everyday users can collaborate to uncover the hidden drivers of health and disease. Each device in the OpenVitals platform is designed to generate high-quality, structured data — from air quality and respiration to biological signals — feeding into a shared knowledge base that supports early detection, prevention, and personalized care.
