Umpire is being built in vanilla PHP, HTML, JS, CSS, and SQL, backed by a MySQL database. The intent is to distribute the system as #FOSS, and have instances around the world federate with each other much like #ActivityPub instances do. We already created a different application (written in Python and SVG) that can extract the data and turn the people's profiles into paper posters and social media posts. We seek to keep the tech stack as straightforward as possible, to allow easy collaboration.
