Most "warehouse design software" is really general-purpose CAD or diagramming that you bend into shape for racking. RackCity is the opposite: a purpose-built pallet rack design software and online pallet position calculator that already understands flue space, back-to-back pairs, column burying, speed bays, and dead bays. That domain awareness is what lets you run a quick racking-layout feasibility check — validating aisle widths and position counts before you commit to steel — in minutes instead of days.

How designing in RackCity works

A typical session, start to finish:

Open RackCity in your browser. No install, no plugin, no CAD license. Enter your email and you're in.
Enter building dimensions. Length, width, clear height. Form fields, about 30 seconds.
Place the column grid. Set bay spacing in feet and RackCity handles placement.
Drop in obstructions and doors. Click and drag to add offices, dock doors, and exits.
Sketch a zone. Drag a rectangle and RackCity fills it with rack rows automatically — back-to-back, single, or double-deep, per your config.
See the count. Pallet positions update live. Change an aisle width and the count reflows instantly.
Iterate. Build three layout variants in the time it would take to draw one in AutoCAD.
Export. PDF or PNG for the client; hand off to engineering for the final stamped drawing.

What's built in

A closer look

Screenshots of common configurations built in RackCity:

Back-to-Back

Selective B2B reserve

Standard back-to-back rows with the column grid buried in the flue space and positions counted automatically.

Double-Deep

High-density storage

Double-deep configuration for ~30% more positions per square foot, with reach-truck aisle widths validated.

Multi-zone distribution center layout designed in RackCity

Multi-Zone DC

Mixed-config building

Per-zone rack configs in one building — reserve, pick, and staging — with speed bays along the dock wall.

What works in the browser today

We're honest about the line. For the iteration phase — the part of warehouse design you actually spend your days on — browser-native is already faster than desktop CAD. For the final stamped deliverable, you'll still hand off to AutoCAD.

Great in the browser

2D floor plan layout and rack row generation
Pallet position counting and live reflow
Aisle width validation against forklift specs
Column-aware rack burying; speed bays, tunnels, dead bays
Export to PDF and PNG

Still better on desktop

Producing stamped, code-compliant engineering drawings (hand off to AutoCAD)
Very large files with tens of thousands of objects
Complex 3D rendering and walkthroughs
