Archi® is a free, open source, cross-platform tool to create ArchiMate models.

The Archi® modelling tool is targeted toward all levels of Enterprise Architects and Modellers. It provides a low cost to entry solution to users who may be making their first steps in the ArchiMate modelling language, or who are looking for a free, cross-platform ArchiMate modelling tool for their company or institution and wish to engage with the language within a TOGAF® or other Enterprise Architecture framework.

Since its introduction, Archi has been widely adopted for real-world use in the commercial and educational sectors and is used in-house by major global companies and consultants. It is the de facto open source ArchiMate modelling tool.

The ArchiMate® modelling language is an open and independent Enterprise Architecture standard that supports the description, analysis and visualization of architecture within and across business domains.
