Modeling workspace
Architecture work without the hand-offs
Move from an idea to a validated, reusable model in one browser workspace.
Native file exchange
Open, edit, and save .archimate models for the documented desktop-compatible feature set.
Multi-model workspace
Keep multiple model roots and views open, arrange docked panels, and restore the workspace between sessions.
Validation and analysis
Find invalid relationships, unresolved references, and structural issues before sharing or exporting a model.
Repeatable automation
Create and query model content through a jArchi-compatible JavaScript API with editor IntelliSense.
Local-first continuity
Autosave the workspace in browser storage and choose explicitly when a file leaves the device.
Desktop continuity
Designed to fit an existing Archi workflow
Archi Online uses native .archimate files and treats desktop Archi as
the reference for file behavior, notation, relationship rules, and supported visual details.
- Lossless round trips for the documented supported feature set
- ArchiMate relationship rules derived from Archi compatibility data
- Read-only viewer links for architecture reviews

Practical details
Questions before opening a model
What is Archi Online?
Archi Online is a browser-based ArchiMate 3.2 modeling application for creating, editing, validating, and scripting enterprise architecture models.
Can Archi Online open files from desktop Archi?
Yes. Archi Online opens and saves native .archimate files for the documented supported feature set, so models can move between Archi Online and desktop Archi.
Where is my model data stored?
Model data stays in your browser by default using local browser storage. Files are uploaded only when you explicitly choose a sharing workflow.
Do I need to install Archi Online?
No. Open the editor in a modern browser, or install it as a progressive web app when your browser offers that option.
Is Archi Online free and open source?
Yes. Archi Online is open-source software released under the MIT License and can be used without charge.
