It has a material-UI frontend that lets users create and self-service their own secret Santa games. The frontend is implemented in ReactJS and the backend is implemented with a Spring Boot server and some Corda flows.
You can create a game using the web frontend (or just calling the API directly with Postman), and once the game is stored, players can look up their assignments using their game id, and the app also supports an optional SendGrid integration so that you can have emails sent to the players as well.
