Free CargoWiz alternative: DimPack3D
CargoWiz is a Windows desktop container-loading calculator that positions itself as the easiest to learn. It has a drag-and-drop editor, Excel import, and a "Spread My Cargo" function for weight distribution, with a fully-featured 30-day trial download.
Compare the workflow you need: import a carton list, plan a load, prepare a pallet quote or hand instructions to the warehouse. The tools differ in scope; this is not a ranking or a claim that every feature is equivalent.
