Best Warehouse Design Software in 2026: 7 Tools Ranked Honestly

RackCity AI is the one tool on this list built for pallet rack layout and nothing else. Draw the building, drop in columns, doors and obstructions, sketch a zone, and it packs the racking: single-deep, back-to-back or double-deep rows, columns buried in the flue, speed bays, tunnels and dead bays, with the pallet position count updating as you go. Change the aisle from 12 ft to 10 ft (3.7 m to 3 m) and the rows reflow in front of you. It runs in the browser; there is nothing to install and no CAD to learn.

Forky AI, the built-in chat, drafts the whole layout from one sentence ("200 by 400 ft, 32 ft clear, 24 by 48 ft column grid, reach trucks") or from an uploaded building flyer (a PDF or a photo of the plan), and you edit from there. Metric mode paints metres, mm and kg with an EU catalog: 900–1,200 mm frames and 2,700, 3,300 and 3,900 mm beams for different pallet widths. In our own use a layout that takes an afternoon of rectangles in AutoCAD takes minutes here; that's our estimate, not a benchmark.

Where it stops: the exports are a Layout PDF (floor plan plus an elevation per rack type), a Bill of Materials as CSV or Excel, and a Pricing Summary PDF, not a stamped .dwg, so a permit set still goes through AutoCAD. The floor plan is 2D, with a 3D view of an individual rack bay on paid plans. All plans support selective, drive-in, push-back, cantilever, carton flow and wide-span shelving; pallet flow, mobile racking and pallet rack on a mezzanine deck are not supported (a mezzanine footprint, with shelving under or on it, is). The first AI design needs no account, and continuing, saving and exporting need a free one; the Free plan is $0 with a limited number of AI requests and one cloud project, exports start on Solo at $29/mo (watermarked) and are clean on Warehouse Pro at $99/mo.

AutoCAD is what most warehouse architects and engineers actually use, for a good reason: it produces real engineering drawings, and every fabricator, permit office and MEP engineer can open a .dwg. If a drawing has to be stamped or handed to a contractor, this is the file they expect.

It knows nothing about pallet racks. A rack row is rectangles and lines you drew. The position count is a calculator. Narrowing the aisle means moving every row by hand and redrawing what no longer fits. At $1,865 a year plus the hours, most of the cost isn't the license, it's the redrawing.

Use it for the deliverable. Do the iteration somewhere else.

SketchUp is where designers go for 3D without the AutoCAD price. It's quick to pick up, and the 3D Warehouse library has thousands of warehouse-adjacent components: forklifts, dock levelers, and some pallet rack frames if you search for them.

It's a general 3D modeler, not a racking tool. No position count, no aisle rules, no column-burying logic. You can spend an afternoon placing rack components by hand to answer a question ("how many positions fit in this zone?") that a rack tool answers as you draw the zone. Use it for the client walkthrough after the layout is settled.

RackPlanner was one of the first tools that understood pallet racking. Frame depth, beam length and aisle clearance are real inputs, it generates rows from them, and it counts positions. For years it was the only purpose-built option.

In 2026 it's Windows-only desktop software with an interface from the late 2000s: one user, no browser, no collaboration, and no clean path to modern CAD formats. If you already run it and work alone, it does the job. If you're choosing today, you'll feel its age in the first hour.

The head-to-head RackCity AI vs RackPlanner comparison goes feature by feature.

Visio ships usable warehouse stencils, most office staff already have it through M365, and a diagram from it drops straight into a PowerPoint deck. For a feasibility study or a management meeting, that's enough.

It isn't a design tool. Nothing enforces scale, there is no position math, and a rack stencil is a picture with no frame depth or beam length behind it. Send a Visio diagram to a steel supplier for a quote and the first reply will be a list of questions.

SmartDraw runs in the browser, comes with warehouse layout templates, and costs under $10 a month. For someone who has never opened CAD and needs a picture for an operations meeting, it's a fair starting point.

The limit is the same as Visio's. The rack shapes don't carry real dimensions, the templates don't know what a flue space is, and nothing counts. Use it for the slide, not for the drawing that drives a steel order.

Revu is on the list because warehouse designers use it every week, but for a different job than the rest. You bring in an existing floor plan PDF and dimension, annotate and red-line on top of it. For coordination and submittal markups it's the standard.

It can't start from building dimensions and produce a layout, and it doesn't try to. A 60-page PDF set that needs comments: Revu. A blank building that needs racking: something above it on this list.
