Source

Lua is free software distributed in source code. Lua may be used for any purpose, including commercial purposes, at absolutely no cost.

The current version is Lua 5.2 and its current release is Lua 5.2.0.

Binaries

Lua is implemented in pure ANSI C and compiles unmodified in all platforms that have an ANSI C compiler. Lua also compiles cleanly as C++. If you have trouble building Lua, read the FAQ. If you don't have the time or the inclination to compile Lua yourself, get a binary or try the live demo. If you use Windows, try Lua for Windows, an easy-to-use distribution of Lua packed with several useful libraries.

Tools

The lua-users wiki lists many user-contributed addons for Lua, including tools, libraries, full distributions, and binaries for several platforms. LuaForge is the major repository for user-contributed tools, and includes LuaBinaries, a complete repository of pre-compiled Lua libraries and executables. Many Lua modules are available as LuaRocks.
