IcePanel
Collaborative diagramming for software architecture.
IcePanel is a browser-based collaborative diagramming and modelling tool for software architecture. It helps software engineering and product teams replace scattered diagrams with a shared model of their systems, supporting both current-state documentation and future-state design. The platform uses the C4 Model and provides dynamic views, overlays, and flows so teams can explore architecture at different levels of detail.
Core capabilities include modelling with C4 levels, landscapes and domains, message flows, tags, and object links. Teams can fork designs, annotate with comments, merge approved changes, and track versions. AI features include generated descriptions, object summaries, and an MCP server for connecting IcePanel with LLMs such as Claude, Cursor, Codex, and VS Code. Integrations cover Confluence, Notion, SharePoint, Miro, EventCatalog, Seezo, webhooks, and a REST API, with exports to Mermaid, PlantUML, PNG, PDF, JSON, CSV, HTML, and LLMs.txt.
IcePanel is packaged with a free plan for up to five editors with unlimited viewers, a 14-day trial on Growth, and paid Growth, Scale, and Enterprise editions based on editor seats. Higher tiers add features such as decision records, audit logs, advanced API usage, webhooks, SSO, custom data residency, and single-tenant environments.
