Iris
An architecture modelling tool that stores the architecture as data, not diagrams.
Most architecture tools treat the diagram as the source of truth, so models drift as they grow. Iris keeps elements, relationships and models in a knowledge graph, and diagrams are views onto it. It supports UML, ArchiMate and C4, and converts from Sparx EA.
An MCP server lets agents query and extend the repository directly. This site is rendered from an Iris collection at build time, so the page you are reading is a working example.
