Cubyz: a Zig voxel sandbox

Cubyz is a 3D voxel sandbox inspired by Minecraft. It is written in Zig, a small language with a focus on readability. The project supports Windows and Linux; Mac is not supported due to the absence of OpenGL 4.3.

From Java to Zig

Until August 2022 Cubyz was written in Java, with code preserved in the Cubyz-Java repository. The Zig rewrite started then. It is now maintained by IntegratedQuantum, who also handles releases and Discord announcements.

Features

The project highlights level-of-detail rendering (enabling far view distances), 3D chunks with no height or depth limit, and procedural crafting that allows infinite tool crafting. Mod support exists via the mods directory and rotation modules.

How to run

The easiest path is downloading the latest source zip, extracting it, and running run_linux.sh or run_windows.bat. A compiled version requires a compatible Zig version and can be built with zig build run. No external tool installation is required for basic play.

FAQ

What language is Cubyz written in?
Zig.

What was it before?

What is the license?
GPL-3.0.

Who maintains it?
IntegratedQuantum, after creators zenith391 and ZaUserA.

Bottom Line

Cubyz is a compact, actively maintained voxel sandbox rebuilt in Zig with strong render distance and procedural crafting. 3.7k stars and 250 forks signal real interest. Run from source with one script.
