Quick Setup (< 1 hour)

You can use IcePanel to create collaborative software architecture diagrams using the C4 model. It helps teams document their system architecture in a structured way with different levels of detail. You can design current and future system states, add message flows to show data movement, and share interactive diagrams with stakeholders. Teams can comment, provide feedback, and iterate on designs before implementation. The tool consolidates scattered architecture documentation into one unified model that serves as the single source of truth.
