 Cuberite is a Minecraft-compatible multiplayer game server that is written in C++ and designed to be efficient with memory and CPU, as well as having a flexible Lua Plugin API. Cuberite is compatible with the vanilla Minecraft client.
 
 Cuberite can run on Windows, *nix and Android operating systems. This includes Android phones and tablets as well as Raspberry Pis.
