Object-centric process mining (OCPM) addresses the limitations of traditional case-centric process models by capturing complex interactions between multiple object types. However, the advancement of OCPM is often hindered by the difficulty of obtaining high-quality, multi-object data from organizations, heavily necessitating simulation logs. While CPN Tools has long been the primary choice for such tasks, it lacks native support for object-centric constructs and the OCEL 2.0 standard, requiring users to manually implement complex time and data handling logic in Standard ML. This paper presents OCPN Studio, a modern, web-based environment designed specifically for modeling, simulating, and analyzing Object-Centric Petri Nets. By abstracting the underlying CPN formalism and providing native support for object types and date/time constructs, this open-source tool simplifies the modeling process. Our browser-based solution supports hierarchical nets, state-space analysis, and seamless OCEL 2.0 export, lowering the entry barrier for researchers, practitioners, and students alike.
