What is Lute?

While Luau is a powerful scripting language, it is sandboxed and primarily embedded in a larger program, like the Roblox game engine. This means it lacks built-in capabilities for interacting with the outside world. Lute fills the gap by providing a standalone runtime for Luau, designed for general-purpose programming outside of game engines. Think of it like Node.js or Deno, but for Luau.

How can I use it?

Lute provides a rich set of built-in APIs for common programming tasks: file system access, HTTP networking, cryptography, process management, and more. You can use these APIs to build a wide variety of applications, from command-line tools to web servers to automation scripts and more. These capabilities come in the form of a set of low-level libraries exposed to Luau under the @lute require alias, and a higher-level standard library built on top of those, exposed under the @std alias. For Roblox developers, we're working hard to ensure the Roblox game engine will support this same set of @std APIs in the future, so you can write code that runs both in Lute and Roblox with minimal changes.
