IcePanel is an interactive modelling and diagramming tool that uses the C4 model to help you communicate your team's system architectures in a structured way. It helps explain how things work to your audiences through an abstraction-first approach, overlaying details when needed. With the C4 Model, you can drill down or zoom in and out of different levels of detail, depending on the audience you're communicating your designs to. In most software teams, this is a mix of technical (developers, architects, operations, etc.) and non-technical people (product, business stakeholders, etc.). Using modelling instead of diagramming alone removes much of the maintenance headache of keeping multiple diagrams up-to-date, as changes sync automatically through all your diagrams.
