Rack Maker helps you plan a homelab rack before you build it. Pick a 10″ or 19″ rack, a DeskPi RackMate or wire shelving, place your devices in 3D, and check what fits. Rack Maker then gives you the parts list, a quote and STL files for the parts you print.

Everything it knows about hardware comes from a shared catalog of racks, mounts and devices. If your device is missing, the device modeler turns your measurements into a 3D model with its ports. Your own AI agent can do the measuring for you.

Three stepsCopy Anchor Link

1. Start a project on Projects: from a template, like the RackMate TL1 or an 8-node DGX Spark cluster, or from an empty 10″ or 19″ rack. Creating one needs an account; opening one someone shares with you doesn't.
2. Place parts. Drag them from Parts onto the 3D view or the elevation, or click a part and then a place. Select anything to change it in the Inspector.
3. Check and build. The checks say what doesn't fit, BOM & quote prices what to buy, and Printed parts exports the STLs.

Your first project walks through these steps in more detail.

Each tour takes about a minute and points at the real screen.

The editor tour runs inside a project: open a project and press ? in its toolbar.

For AI agentsCopy Anchor Link

Rack Maker's device modeler can be driven by your own AI agent over MCP. Using AI agents explains how to connect it and what it can do.

These docs are also available as plain Markdown: /llms.txt lists every page, and Docs for agents explains the other formats.
