Kubova vs Stack-IQ

Kubova is a web and API service for planning how cargo fits into containers and pallets. It calculates capacity, produces an inspectable CAD-style 3D loading plan with exact placements, and can create shareable PDF reports. The calculator handles multiple SKUs and cylinders, standard or custom containers, and mixed container types. Its packing engine uses real container dimensions, payload limits, and gravity, while identifying items that spill over because they do not fit. The REST API accepts cargo and container data and returns placements, used volume, and unplaced pieces; API access is available on Pro and above. MCP guidance lists Claude, ChatGPT, Cursor, Cline, and VS Code as compatible clients. Free provides 50 packs and 20 PDF reports monthly. Pro costs $29 a month; Team costs $69 a month. Enterprise pricing is custom.
