It helps players customize their data center builds with additions spanning core systems, visuals, automation, networking, racks, and hardware. The site’s categories include shared framework services such as gregCore, user interface components, and save/load tools; HUDs, overlays, themes, and other interface improvements; and automation features for building, monitoring, and worker logic. Networking projects can add tools for IP address management, VLANs, cable routing, switch behavior, and flow analysis, while hardware mods introduce racks, servers, switches, modules, and variants.
