Archi

Archi is an open‑source toolkit for building ArchiMate models and sketches. It implements the ArchiMate® 3.2 language, allowing users to place elements, define relationships, and organise them into views and viewpoints that match the needs of different stakeholders. The interface includes a “magic connector” that ensures correct linking of concepts, a Hints view that explains elements and relationships, and support for custom properties and colour schemes to refine diagrams.

The application targets enterprise architects, modelers, and anyone working within TOGAF or other architecture frameworks, from beginners to experienced professionals. It is used by organisations such as banks, insurance firms, consulting practices, training providers, universities and students. Because it is cross‑platform and free, it offers a low‑cost entry point for teams that require an open‑source solution for architectural description, analysis and visualisation.

Key features include dedicated support for ArchiMate views and viewpoints, a visualiser for interactive diagram navigation, a sketch view for quick ideas, and a canvas‑modelling toolkit for larger projects. The stable macOS build is part of a broader, regularly downloaded user base, and development is maintained by community contributions.
