Free PackApp alternative: DimPack3D
PackApp is a load planning application for trailers, containers and railcars that suggests one or more load plans from a packing list, including paper rolls, pallets and skids, and exposes a REST API for ERP/TMS integration.
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.
