FloorCast3D as a OneRack alternative
These are the two tools in this category that both draw the rack and count it. The honest summary: OneRack is the closer competitor and the cheaper one, and the question is whether you would use the two things it does not publish.
| FloorCast3D | OneRack | |
|---|---|---|
| Price | $199/mo | $150/mo |
| Load-estimate BOM | Yes | Yes |
| Permit pre-flight + placards | Yes | Partial |
| Flow / throughput simulation | Yes | not offered |
| CAD + simulation, one tool | Yes | not offered |
“×” means the vendor does not publish the capability — not that it is impossible. US list, excluding tax. Prices were checked against the vendor’s own page on 19 July 2026, US list, excluding tax, and software pricing moves — verify the current figure with OneRack rather than trusting this page.
Where the two overlap
More than most comparison pages will admit. Both tools treat the layout as data rather than line work, and both turn it into a load-estimate bill of materials instead of leaving the takeoff to a spreadsheet. If your requirement stops at “draw the racking and tell me what it costs”, you are choosing between two tools that genuinely do that, and the rest of this page is about the margin.
When OneRack is the better choice
It is $150/mo against $199/mo, so if you would not use the simulation or the permit pre-flight you are paying for capability you do not need, and that is a bad trade at any quality. Buy the cheaper tool.
It also derives seismic criteria from the project address and sizes to a design load. If seismic criteria are the part of your work that hurts most, that is a direct answer to it, and it is the reason OneRack earns a Yes rather than a qualified one in the table above.
When FloorCast3D is the better choice
Two situations, both about what happens after the layout is drawn. The first is permitting: FloorCast3D reads the layout against the jurisdiction and returns a categorized, cited checklist of what the arrangement triggers, then writes the whole submittal package — drawings, BOM, placards, preliminary forms and the checklist — as one ZIP. The permit guide walks through what that contains and who signs which part of it. If “somebody notices it is high-pile” has ever landed on one of your jobs after the quote was accepted, that is the gap this fills.
The second is when the argument is about flow rather than capacity. A layout can be correct on paper and still be a bad building to work in, and the only honest way to find that early is to compare two candidate designs before either is steel. FloorCast3D runs that comparison against the same object it drew, which is the row in the table above that no other column answers. It is comparative, not predictive — it will not forecast your throughput, and any tool that offers to is overselling.
How to actually decide
Do not decide from this table, or from theirs. Take one job you have already quoted — where you know what the steel cost and what the plan checker said — and run it through both tools. Compare the packages that come out, not the feature lists that go in. If you want to judge FloorCast3D’s output before installing anything, the sample submittal package is a real one, generated by the product.
Frequently asked
What is the main difference between FloorCast3D and OneRack?
Both produce a rack layout and a load-estimate bill of materials, so the difference is what surrounds that. FloorCast3D adds a flow simulation and a permit pre-flight in the same tool that draws the sheet, so one object produces the drawing, the count, the price, the code checklist and the throughput comparison. OneRack concentrates on the engineering side of the layout and does not publish throughput simulation or high-piled storage screening.
Is OneRack cheaper than FloorCast3D?
Yes. OneRack lists at $150/mo against FloorCast3D at $199/mo, both US list excluding tax as read on 19 July 2026. If the simulation and the permit pre-flight are not things you would use, that difference is real money and you should weigh it honestly.
Does OneRack do seismic?
It sizes to a design load and derives seismic criteria from the project address, which is a genuine strength and part of why it earns a Yes on load-estimate BOM in the table above. What it does not publish is high-piled storage screening or throughput simulation.
Can I try FloorCast3D before switching?
Yes, and you should. The trial key is the whole product for 14 days with no card, exports watermarked until you subscribe. Run one of your own past jobs through both and compare the packages rather than the feature lists.
