Moonstone is a modern, cross‑platform Lua runtime and package manager written in the Zig programming language. It aims to bring the simplicity of Lua development to multiple operating systems while leveraging Zig’s safety guarantees and compile‑time performance.

The runtime provides fast startup times and low memory overhead, making it suitable for embedded scripts and server‑side applications. Its built‑in package manager simplifies dependency handling, allowing developers to install, update, and remove Lua modules with a single command.

A recent Hacker News submission highlighted the project, earning 4 points but attracting zero comments so far. The post links to the official site and the discussion thread, showing early curiosity from the community.

Developers interested in trying Moonstone can visit moonstone.sh for documentation and download links. As the tool matures, it could become a viable alternative to existing Lua runtimes, especially for those who prefer a Zig‑based stack.

Because Moonstone is implemented in Zig, it benefits from manual memory management without a garbage collector, deterministic deallocation, and easy cross‑compilation. This design choice reduces runtime dependencies and simplifies deployment across Linux, macOS, and Windows.
