Luau is a fast, small, gradually typed scripting language derived from Lua 5.1, designed to be embedded in applications with a sandboxed runtime and Lua-compatible C API. It ships with a REPL/runner CLI and a static analysis tool (luau-analyze) for type checking and linting.
Use cases
- embed a scripting language in a game or application
- write typed Lua scripts with type inference
- run untrusted user scripts safely in a sandbox
- lint and type-check Lua-like codebases
- script Roblox game logic
- replace Lua 5.1 with a faster, safer runtime
When to choose
- you need an embeddable, sandboxed scripting language with gradual typing
- you want Lua 5.1 compatibility with better performance and type safety
- you are building Roblox experiences or games adopting Luau
When to avoid
- you need a general-purpose standalone systems language
- you require full compatibility with newer Lua versions like 5.4
- you need a large standard library out of the box
