Warehouse Planning and Mapping Software: Which Kind Do You Actually Need?

The short answer

Three questions get asked under the name "warehouse planning":

• What goes where on the floor? Racking rows, aisles, docks, offices, and how many pallets the building holds. That is layout planning. A rack layout tool answers it; we build one, RackCity AI, and it is the category this page knows best.
• What is each location called? Aisle 04, bay 12, level C — the addresses a warehouse management system uses to put stock away and pick it. That is location mapping, and it comes with the WMS, not with a drawing tool.
• How will the operation perform? Orders per hour, picker travel, dock congestion, before the building opens. That is modeling, or simulation, and it is engineering software with an engineering price.

Most people searching this phrase need the first one and are being shown the third. The rest of this page is about telling them apart, and about what the browser can and can't do for each.

The three categories, and what each one costs

1. Layout planning software

The building on a canvas, racking placed on it, a count of what fits. The inputs are dimensions, clear height, the column grid, the docks, the pallet and the forklift; the outputs are a floor plan, an elevation drawing, a pallet-position count and a bill of materials. This is what a rack dealer, a warehouse manager sizing a lease, or a broker answering "how many pallets fits?" needs. Generic CAD (AutoCAD, at roughly $2,000 a year) can draw it but knows nothing about racking, so every row and every count is manual. Rack-aware tools do the placement and the counting; RackCity AI is one, browser-based, free to start, $29 or $99 a month with exports. The comparison table puts the options side by side.

2. Warehouse mapping software

The word "mapping" is where the confusion starts. In operations it means the WMS location map: every rack bay, beam level and bin given an address so a scanner can direct a picker to it. That map lives inside the warehouse management system — Manhattan, Blue Yonder, SAP EWM, NetSuite, or a smaller one — and is built during WMS implementation, from the physical layout. In planning, "mapping" just means drawing the floor. If you need addresses for a scanner, you need the WMS; if you need a drawing of where the racking goes, you need a layout tool, and the WMS map is built from it afterwards.

3. Warehouse modeling and simulation software

Simulation tools — FlexSim, AnyLogic, Simio, and the warehouse modules of the big engineering suites — take a layout and an order profile and run the operation forward in time: how many picks an hour, where trucks queue, whether a conveyor keeps up. They are the right tool for a large automated facility and for choosing between pick methods, and they are priced for that work (licences run from several thousand to tens of thousands a year, plus the engineer to build the model). "3D warehouse modeling software" usually means this, or means SketchUp used to make a walkthrough for a presentation. Either way, a simulation starts from a layout; it doesn't produce one.

Why browser-based matters for layout planning

Layout planning is the category where "online" stopped being a compromise. The work is two-dimensional, the files are small, and the value is in iteration — three versions of the aisles before lunch — which is exactly what a browser tool is good at. Four things it removes:

No install, no licence server

A URL instead of an IT ticket. No seat to wait for, no licence server to lose a Tuesday to. A new hire gets a link.

Any machine

Windows, Mac or Linux, the same tool and the same projects. A dealer on a laptop at the customer's site opens the same layout the office drew that morning.

Projects that stay together

Cloud projects hold the design, its versions and the files exported from each — the floor plan a customer approved and the quote that went with it, still there when they call back in six months.

Units that follow the reader

RackCity AI works in feet and inches or in metres and millimetres, with a rack catalog for each; a design drawn in Chicago reads in metric in Rotterdam without anyone converting anything.

What you can actually do online in 2026

What works in the browser

• The floor plan: building, column grid, docks, offices, walls
• Rack rows placed at the aisle width you set, for single-deep, back-to-back and double-deep racking
• The pallet-position count, live, per zone and in total
• Columns buried in the flue space, dead bays and cross tunnels
• An AI that drafts the layout from a sentence or from the building's flyer, as a PDF or a photo
• Exports: the Layout PDF with an elevation per rack type, the bill of materials as CSV or Excel, a Pricing Summary PDF

What still lives on the desktop

• The stamped, code-compliant engineering set — the engineer produces it, usually in AutoCAD, from your layout
• Rack types a layout tool doesn't model yet — for RackCity AI that is pallet flow, mobile racking and pallet rack on a mezzanine deck (drive-in, push-back, cantilever and carton flow are in since v1.5; mezzanine footprints with shelving under or on the deck are drawn)
• Simulation and 3D walkthroughs, for the reasons above
• Working with no connection at all

For the planning phase — the "what if the aisles were 10 ft" phase, the position-count negotiation with the client — the browser is the better place to be. The deliverable phase still ends in the engineer's CAD.

What planning a floor in RackCity AI looks like

1. Open the app. Nothing to install; a free account when you want to save.
2. Enter the building — length, width, clear height — or drop in the landlord's flyer and let it be read off the page.
3. Set the column grid, pasting the bay widths off the architect's drawing if they are uneven.
4. Draw the docks, the office and any walls the racking has to keep clear of.
5. Draw a zone and pick the rack type; the rows fill it at the aisle you set, and the count appears.
6. Iterate: five levels instead of four, 9 ft aisles instead of 12, double-deep at the back. Read the count each time.
7. Export the floor plan and the bill of materials, and hand the layout to the engineer for the stamped set.
