The multi-agent software platform DIET¹ provides components to implement open, robust, adaptive and scalable ecosystem inspired applications. The development, debugging and monitoring of decentralised systems is a complex process. Adequate techniques and tools are required to assist the application developer. This paper describes the outline of a platform for visualising ecosystem inspired applications. The architecture provides fundamental components and functions extending the DIET core layer by visual and interactive components. These will allow the introspection and manipulation of applications built upon DIET without the need for changing any application code.
