Icepanel

IcePanel is a browser-based tool for building and maintaining software architecture diagrams using the C4 modeling methodology, pitched as a single source of truth replacing scattered diagrams. The headline "Model your architecture for humans and agents" pairs technical diagramming with newer agent-facing positioning. Trust signals are dense for a tool this specific: Y Combinator backing, logos from Cisco, BMW, and Cambridge University, and a carousel of 17 attributed testimonials from named Principal Engineers and CTOs, alongside SOC 2, ISO 27001, and GDPR badges. The tone is notably informal for enterprise software, with copy like "no added bull" and a dedicated comparison section naming Visio, Lucidchart, Miro, and Structurizr directly.
