BoardGameOnline/BGO is an online multiplayer site which uses the Spring framework, designed to be versatile and extendable. It currently includes tic tac toe, checkers, and connect 4. It was made in 2020. An instance is hosted here (with limited functionality due to the hosting plan).
The online version uses a basic free plan and does not run properly. If you want to see this fully in action, you'll need to run it locally (or give me a nicer server).
The app uses gradle to startup. It expects a postgresql database.
