The present disclosure relates to methods of systems for process modeling. Embodiments of the present disclosure may store a user interface framework in a memory allocated to a browser application in the computer. The user interface framework may provide a user interface to a user operating the computer to perform process modeling. Some embodiments may also render the user interface using a rendering engine associated with the browser application and capture one or more process modeling events received as input by the user. The one or more process modeling events may be associated with one or more process models. In addition, some embodiments may store the one or more process modeling events as model data in the memory allocated to the browser application and render the one or more process models on the user interface based on at least a subset of the model data.
