Luau C API

Unofficial documentation of the Luau C API. Much of the Luau API is identical to the Lua 5.1 API. However, there are many additions, removals, and changes within Luau. Using the Lua 5.1 docs exclusively is not sufficient.

API Reference

The Reference page contains documentation on the Luau C API.

Guides

The Guides page contains various how-to guides for extending Luau, such as creating efficient userdata types, using native code generation, sandboxing, and much more.
