Lua Showcase

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

World of Warcraft Celestia Grim Fandango Nmap
Players of World of Warcraft use Lua to customize the game interface. Celestia is a real-time 3D visualization of space that can be scripted with Lua. "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) Nmap, a popular tool for network discovery and security auditing, is scriptable with Lua.
Angry Birds Hammerspoon Neovim Blackmagic Fusion
The widely popular game Angry Birds is mostly written in Lua. See a talk by Jaakko Lisalo at the Game Design Expo 2011. Hammerspoon is a tool for powerful automation of macOS using Lua scripting. Neovim is a popular hyperextensible Vim-based text editor that supports Lua plugins. Blackmagic Fusion, a post-production image compositing software used extensively in the movie industry, uses Lua as one of its embedded scripting languages.
