Time to value

Quick Setup (< 1 hour)

You can use IcePanel to map and document complex system architectures using the hierarchical C4 model. Instead of maintaining static, out-of-sync diagrams across different apps, you create a shared technical source of truth. You can zoom in and out between high-level context and low-level code components, step through message flows to visualize data movement, and fork designs to draft future changes before merging them. Engineering teams and stakeholders can review proposals, leave comments, and track architectural decisions as systems evolve over time.

What IcePanel does

Create hierarchical system architecture diagramsFork architecture models to plan upcoming system modificationsTrace message flows between application services and databasesLeave review comments on proposed architectural changesFilter system views by metadata tags and abstraction levelsMerge approved technical designs into the primary architecture modelInteractive multi-level zoom based on the C4 modelBranching and merging system models for future planningAnimated message flows to show communication pathsCentralized entity catalog that keeps all diagrams synchronizedCustom metadata tagging to filter diagrams by audienceInteractive commenting and review workflows for design proposalsFree read-only access for stakeholders
