Lua Showcase

Lua is used in many products and projects around the world. Here are some highlights. A different selection is shown every day.

GitHub Solar2D Grim Fandango World of Warcraft
GitHub uses Lua scripts in the infrastructure of GitHub Pages, its static site hosting service. Solar2D is a free Lua based game engine with focus on ease of iterations and usage. It is a fork of the well established and widely used Corona SDK game engine. "Grim Fandango was the first game that shows Lua could not only be used to make a good game, but that it could be used to make some of the best games ever." (cited here; see also this) Players of World of Warcraft use Lua to customize the game interface.
