Open Hospital

Open Hospital is a free and open-source Health Information Management System and Electronic Health Record application. It is used by hospitals and NGOs, often in developing countries, to manage medical records from a desktop application.

It runs in a portable standalone mode for a single user or a client-server mode where multiple clients connect to one database server. The application is written in Java with a Java Swing interface, runs on low resources, and is designed to work without an internet connection. Its components include Core for business logic, GUI for the desktop interface, plus a REST API and a React web UI that are still work in progress.

Open Hospital ships as portable or all-in-one packages distributed through GitHub and SourceForge, and runs on Windows, macOS, and Linux. It can be used offline in portable mode or deployed on a local network, with no cloud service required.
