MCServer 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. MCServer is compatible with the vanilla Minecraft client.
Hosted MCServer is available DIY on DigitalOcean: [![Install on DigitalOcean](http://doinstall.bearbin.net/button.svg)](http://doinstall.bearbin.net/install?url=https://github.com/mc-server/MCServer) and [Gamososm](https://gamocosm.com) also offers MCServer support.
For other operating systems you need to download and compile yourself. There is also an archive of binary builds on the buildserver: http://builds.cuberite.org
Compiling the server yourself has other benefits: you may get better performance performance (1.5-3x as fast) and it supports more operating systems. See the [COMPILING.md](https://github.com/mc-server/MCServer/blob/master/COMPILING.md) file for more details.
