Molecular dynamics has emerged as a powerful and efficient tool to study soft matter. As the computing power available increases, so does the complexity of studied systems. In order to perform a simulation, initial positions and topologies must be built. A few tools already exist, but are generally very specific in terms of systems they can build. Here, we introduce Hoobas, a molecular building tool able to handle very general systems and nearly arbitrary polydispersity using a prototype-builder design pattern. As examples, we show building of DNA-coated colloidal crystals, lipid membranes and random hyperbranched polymer melts. The objects provided are easily extensible to other topologies.
