Runeline is a factory building game where you write real code to automate magical machines and optimize complex production chains.

Inspired by automation and programming games, Runeline challenges you to think like both an engineer and a spellcaster.

Build machines by combining specialized components into working production systems. Every design choice matters.

Will you create highly specialized machines packed with modules for maximum throughput, or flexible assemblies that handle many recipes more slowly but efficiently?

Balance limited power, space, and resources as you scale your factory and refine your designs.

Machines don’t run themselves: you control them with code.

Write programs in a simple assembly-style language to coordinate modules, route resources, and solve production bottlenecks. As your factory grows, your code must grow smarter and more efficient with it.

Use code-driven spell systems to fight enemies, protect your factory, and eventually automate construction itself, turning your factory into a self-expanding machine.
