Source Control for BPMN

Does anyone know of a source control / code repository that integrates bpmn-js? I would love to be able to manage models the same way I manage code (forks, version control, issues, etc.) except using bpmn-js as the visual diffing tool and designer in the browser. Anyone seen anything like this out there? It would greatly ease collaboration on bpmn models and upkeep on models with members of the business.

Hi,

Camunda just launched a SaaS product for collaborative design of process models called Cawemo. Version control is not yet part of it, but it is on the road map. You can check it out here: https://cawemo.com/
