333networks MasterServer is an open-source masterserver software that helps restore online multiplayer support for legacy games that lost service after GameSpy shut down. It receives heartbeats from gameservers, maintains server lists, and provides those lists to game clients using the GameSpy v0 protocol. The project also offers a JSON API to obtain server lists and server data for third-party applications. It is maintained by 333networks, a non-profit volunteer group.
