ComputerCraft is a modification for Minecraft that introduces the ability to both use and program a computer, including extending its functionality with additional blocks. ComputerCraft also uses its own Creative Tab. One of ComputerCraft' appeals is the ability to code applications in Lua.

Other alternatives exist to ComputerCraft; RedPower2 had the ability for the user to craft computers, while OpenComputers is the current active alternative to ComputerCraft that provides similar functionality. NedoComputers also exists, focusing on a more retro-style of computing.

ComputerCraft also has dedicated mods designed purely to supplement its functionality. OpenCCSensors, for example (a fork of the later CCSensors), provides sensors that allow a properly-coded interface to gather a wide variety of data.
