- How to pick the right one
We built RackCity because the existing tools forced warehouse designers into a bad choice: either spend $1,800/year on AutoCAD and three days learning ribbon menus to draw a single pallet rack, or use a "warehouse template" in a generic diagramming tool that doesn't know what a flue space is. Almost nothing useful sat in between.
That's the gap this list is built around. Below are seven tools real warehouse designers reach for in 2026, ranked by how well they actually do the job of laying out pallet racking, calculating positions, and iterating on aisle widths. We'll be upfront about where RackCity sits and where the alternatives genuinely win.

The short version: if you're laying out pallet racking and you want fast pallet position counts without learning CAD, use RackCity. If you need stamped engineering drawings, use AutoCAD. If you need 3D for a client pitch, use SketchUp. Everything else is a compromise.
RackCity
Browser-based pallet racking design with automatic position counts.
RackCity is the only tool on this list built specifically for pallet rack layout, with column-aware row generation, back-to-back / single / double-deep configurations, and automatic pallet position counting. It runs entirely in the browser — there is nothing to install, no AutoCAD license, no CAD experience required.
Draw a building. Drop in columns, doors, and obstructions. Sketch a zone. RackCity generates the racking layout inside it, accounting for column burying, speed bays, tunnels, and dead bays. Change aisle width and the whole layout reflows in milliseconds. Most racking layouts that take 4–8 hours in AutoCAD take 15–30 minutes here.
The trade-off: RackCity is in private preview. It's free, but you need an email signup to access it, and it doesn't yet produce stamped engineering drawings. If you need a permit set, you're still going through AutoCAD afterward.
Pros
- Built specifically for pallet racking
- Browser-based, no install
- Auto-counts pallet positions
- Reflows on aisle/column changes instantly
- Free during preview
Cons
- Private preview (email signup required)
- 2D only — no 3D yet
- Not a permit-grade drawing tool
AutoCAD
The industry standard. Powerful, expensive, and overkill for racking layouts.
AutoCAD is the default tool most warehouse architects and engineers actually use, and for good reason: it produces real engineering drawings, integrates with every downstream construction workflow, and every contractor on the planet can open a .dwg file. If you're handing drawings to a steel fabricator, a permit office, or an MEP engineer, this is the file format they want.
The downside is that AutoCAD doesn't know anything about pallet racks. You're drawing rectangles and lines. Want to know how many pallet positions a layout holds? Get out a calculator. Want to change aisle width and see how it cascades? Manually move every rack row. The hourly economics of this in 2026 are brutal — designers spend more time pushing pixels than designing.
Use AutoCAD for the deliverable. Use something else for the iteration.
Pros
- Industry-standard .dwg format
- Permit-grade drawings
- Massive ecosystem of plugins
- Anyone in construction can open files
Cons
- $1,800+/yr per seat
- No native racking primitives
- Slow to iterate on layout changes
- Steep learning curve
SketchUp Pro
The best 3D modeling option for warehouse pitches — but slow for floor plan work.
SketchUp is the default for designers who need 3D visualization without the AutoCAD price tag. It's genuinely fun to use, the community library has thousands of warehouse-adjacent components (forklifts, dock levelers, even pallet rack frames if you hunt), and the learning curve is gentle.
The problem for warehouse layout work is that SketchUp is a general 3D modeler, not a racking tool. There are no pallet position calculations, no aisle-width rules, no column-burying logic. You'll spend hours arranging rack components in 3D when what you actually want is "tell me how many positions fit in this zone." It shines for client presentations and rough visualizations, not for design iteration.
Pros
- Best 3D rendering in this list
- Huge component library
- Affordable vs AutoCAD
Cons
- No pallet rack logic
- Slow for 2D layout work
- No position counting
RackPlanner
A racking-specific desktop tool from a previous era — still works, just dated.
RackPlanner deserves credit as one of the first tools that actually understood pallet racking. It generates layouts with rack-specific constraints (frame depth, beam length, aisle clearances), and for years it was the only purpose-built option in this space.
The trade-off in 2026 is that RackPlanner is Windows-only desktop software with a UI that feels like 2008. Single-user, no collaboration, no browser access, no real export to modern CAD formats. If you've already standardized on it and your workflow is solo, it works fine. If you're starting fresh, you'll feel the dated experience immediately.
We wrote a head-to-head RackCity vs RackPlanner comparison if you want the full breakdown.
Pros
- Built specifically for racking
- One-time license (no subscription)
- Established workflow
Cons
- Windows-only
- Dated UI
- No collaboration
- No browser access
Microsoft Visio
Cheap and accessible if you already have Microsoft 365 — but it's a diagramming tool, not a CAD tool.
Visio has decent warehouse stencils, integrates with the Microsoft ecosystem, and most office workers already have access through their M365 subscription. For high-level warehouse diagrams in a PowerPoint deck or a feasibility study, it's perfectly fine.
It is not, however, a real design tool. There's no scale enforcement, no pallet position math, no rack-specific behavior. If you submit a Visio diagram to a steel supplier and ask for a quote, expect a long phone call where they explain why the drawing isn't enough.
SmartDraw
Browser-based diagramming with warehouse templates. Better than nothing, but not for engineering.
SmartDraw runs in the browser, has pre-built warehouse layout templates, and is cheap. For someone who needs a visual aid for an operations meeting and has never opened CAD, it's a reasonable starting point.
The catch is the same as Visio's: it's a diagramming tool dressed up with warehouse-themed clipart. The pallet rack shapes don't enforce real rack dimensions. The "warehouse templates" don't know what a flue space is. Use this for slide decks, not for design that's going to drive a steel order.
Bluebeam Revu
Excellent for marking up architect-supplied PDFs — but it's not a layout tool.
Bluebeam Revu is included here because warehouse designers genuinely use it, but it solves a different problem than the rest of this list. Revu is a PDF markup tool — you bring in an existing architect floor plan and annotate, dimension, and red-line on top of it. For coordination work and submittal markups, it's outstanding.
It is not, however, a tool for designing from scratch. If you're starting with raw building dimensions and need to generate a layout, Revu can't help. If you're handed a 60-page PDF set and need to annotate it, Revu is excellent.
How to actually pick the right one
Most warehouse design projects involve more than one of these tools, not because designers love switching context but because no single tool does the whole job yet. A typical 2026 workflow looks like this:
- Layout iteration and pallet counting: RackCity (or RackPlanner if you're stuck on a Windows desktop)
- 3D visualization for client pitches: SketchUp Pro
- Permit-grade drawings and engineering coordination: AutoCAD
- Markup on architect-supplied PDFs: Bluebeam Revu
If you're a small operator doing your own 3PL setup and you don't need permit drawings, you can stop at step 1. If you're a material handling integrator delivering to a Fortune 500 client, you'll touch all four.
The deeper question: design vs deliverable
The reason this market is so fragmented is that "warehouse design software" actually means two different things, and the same tool is rarely best at both:
- Design tools let you iterate fast — change aisle width, swap rack types, move zones, see pallet counts update. The job is exploration.
- Deliverable tools produce the final artifact — stamped drawings, BIM models, permit submittals. The job is documentation.
AutoCAD is a deliverable tool that designers force into a design role and pay for it in hours. RackCity is a design tool that doesn't pretend to be a deliverable tool. Knowing which one you actually need is the entire game.
If you're laying out pallet racking and want fast position counts, aisle compliance, and the ability to test five layouts in the time it takes to draw one in AutoCAD, RackCity is the tool. When the design is locked, hand it off to AutoCAD (or a draftsperson with AutoCAD) for the stamped set.
