Luau
A fast, small, safe, gradually typed embeddable scripting language derived from Lua, used by Roblox and game developers.
What is Luau?
Luau is a fast, small, and safe embeddable scripting language based on Lua 5.1, enhanced with a gradual type system and performance optimizations. It solves the need for a modern, type-aware scripting language in embedded contexts like game engines, where Lua's simplicity is valued but additional safety and tooling are required.
Game developers (especially in the Roblox ecosystem), engineers embedding scripting into applications, and teams needing a performant, type-checkable Lua derivative for large codebases.
Developers choose Luau for its seamless Lua 5.1 compatibility combined with modern features like gradual typing and superior performance, backed by production use at Roblox and other major games, ensuring reliability and active innovation.
