Packly is a web platform for structural packaging design, dieline creation, 3D mockups, and printing. Users can upload artwork for an interactive model that displays finishes such as gold, silver, or varnishes. ShareLinks let others view a packaging model through a link without receiving native files. Studio Mode supports custom thickness from 0.2 to 1.8 mm and a 1200×1700 mm work area, though printing is unavailable in that mode. Plans set monthly or annual allowances for dieline templates and 3D mockups, and unused allowances expire when a subscription period ends. The Basic plan is free and includes three templates and three mockups per month. Light+ costs €37 /month; Pro+ costs €379 /year; Custom starts from €699 /year. A subscription is not required to purchase printed packaging, and Packly says designs can be printed with it or elsewhere. Custom box orders range from 1 to 1 million pieces, with no minimum quantity. Packly also describes APIs for integrating its generators into external applications.
