SLED (Script Language Editor and Debugger) provides a script debugger and runtime, with built-in support for Lua.

The SLED project enables users to create, edit, and debug in-game Lua scripts easily and quickly. It also provides memory tracking and performance-analysis capabilities. Highly flexible, and equipped with an array of powerful features, this toolset can reduce script-development time while helping to increase script performance and robustness. For a list of features, see Features and Benefits.

SLED has been used by several Sony Computer Entertainment first party game studios during their game development, such as Bend Studio, Guerilla Games, and JAPAN Studio.
