Free TOPS Pro alternative: DimPack3D
TOPS Pro (TOPS Engineering) is Windows packaging-design software used by CPG packaging engineers: it sizes primary packs and shipcases, builds pallet patterns, estimates stacking strength and places pallets in trucks.
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.
