LuaDirectory > LuaAddons > Libraries
This is a list of libraries implemented in Lua or implemented in another language (e.g. C) but having a Lua interface. For older libraries and bindings, see the LuaAddonsArchive.
Modules can also be found on LuaForge. Lua ModuleReview intends to arrange some of them.
Note to authors: This page is part of LuaAddons — please read the instructions there before making changes to this list. Please don't mark an entry with an open-ended version (e.g. "5.x"), as it will likely be incorrect the moment a new Lua version is released.
For something to be listed on this page, it must be possible to "require" it into a typical Lua application. Examples of what not to list:
- XYZ server or app that uses Lua for scripting or config
- XYZ engine or framework for C++ apps which is scriptable in Lua (but cannot extend existing Lua apps)
