Lune 🌙

A standalone Luau script runtime.

Write and run scripts, similar to runtimes for other languages such as Node / Deno, or Luvit for vanilla Lua.

Lune provides fully asynchronous APIs wherever possible, and is built in Rust 🦀 for optimal safety and correctness.

Features

• 🌙 A strictly minimal but powerful interface that is easy to read and remember, just like Luau itself
• 🧰 Fully featured APIs for the filesystem, networking, stdio, all included in the small (~4mb) executable
• 📚 World-class documentation, on the web or directly in your editor, no network connection necessary
• 🏡 A familiar scripting environment for Roblox developers, with an included 1-to-1 task scheduler port
• ✏️ Optional built-in library for manipulating Roblox place & model files, and their instances

Non-goals

• Making scripts short and terse - proper autocomplete / intellisense make scripting using Lune just as quick, and readability is important
• Running full Roblox game scripts outside of Roblox - there is some compatibility, but Lune is meant for different purposes
