Ludos is a project which enables players to join any game supported, with servers being created dynamically using the Pterodactyl API if all games are full, or none are available. The project has no donation methods currently.
Ongoing, albeit slow, development from the team with launch hopefully soon.
Languages & Technologies
The game servers run a modified version of PaperSpigot, with the core plugins written in Java. The plugins communicate with the proxies (a modified version of Velocity) using Redis, to coordinate the installation of servers. The proxies then pass the data to the Pterodactyl API.
