How UXXU Desktop works

Local files and cloud projects.
One place to work.

UXXU Desktop brings the architecture workspace to your computer. Use it as a free viewer for local Structurizr DSL, or sign in to access your cloud workspace. Switch between Local and Cloud from the Projects screen.

View local projects for free

Open a Structurizr .dsl file on your computer and explore its architecture. No account, subscription or upload is needed for local viewing, and it works offline.

  • Browse diagram thumbnails and navigate between connected C4 views.
  • Inspect elements, relationships, properties and DSL source.
  • Reopen recent projects or open a folder containing workspace.dsl.

Work with your cloud projects

Sign in with your UXXU account to open your organisations and cloud projects inside the app. Model, edit and collaborate with your team using the same cloud workspace you use in the browser.

  • Your existing cloud plan, project access and permissions apply.
  • Cloud projects stay in the cloud and require an internet connection.
  • Switch back to local files without uploading or automatically syncing them.

Explore the whole model

Move from the project gallery to a diagram, use Diagram Map to find connected views, and inspect the shared object model behind them.

Edit locally with a licence

Sign in with an active editing licence and an editor, admin or owner role to create workspaces, edit on the visual canvas or in DSL source, and save changes to disk. Undo, redo, Save As and autosave support the workflow.

Stay up to date

macOS, Windows and Linux AppImage releases check for updates and ask before restarting to install them. You can also use Help → Check for Updates. Debian / Ubuntu installations are updated by installing a newer DEB package.

Your .dsl files open in UXXU

Installed builds register UXXU as an application for Structurizr .dsl files. Once UXXU is your default app for that extension, double-click a file in Finder or your file manager to open its local project directly.

  1. 1. Install UXXUChoose your operating system and processor above, then install the application. On macOS, move UXXU to Applications before opening files.
  2. 2. Choose it for .dsl filesIf another app opens the file, use Open With → UXXU and make it the default. On macOS, use Get Info → Open with → Change All. On Windows, select UXXU in Default apps for .dsl.
  3. 3. Open and exploreDouble-click your workspace to see its diagram gallery. You can also open a file from inside UXXU. On Linux, associations depend on desktop integration; a standalone AppImage may need that integration first.

Before you get started

Is UXXU Desktop free?

Yes. The local viewer is free and works without an account. Open supported Structurizr DSL files and browse their diagrams. Creating, editing and saving local workspaces requires signing in with an active UXXU editing licence and an editor, admin or owner role. Cloud plans and their limits are separate.

Can I use my existing cloud projects in the app?

Yes. Sign in with your usual UXXU account and select your cloud organisation and project. Your existing cloud plan and permissions apply, including any free-plan limits. The desktop application does not turn local files into cloud projects or sync them automatically.

Will double-clicking a .dsl file open UXXU?

Installed builds register UXXU for .dsl files. Set UXXU as the default application for that extension to open them with a double-click. If another application is already the default, choose Open With → UXXU or change your system's default-app setting. Linux AppImage users may need desktop integration first; opening a file from inside UXXU always remains available.

Do my local files get uploaded?

No. Opening a local workspace does not upload it to UXXU. Cloud projects use the connected cloud service. Optional account-linked usage reporting is off by default and is a separate choice in Help → Desktop Privacy.

Can I work offline?

You can view local files without signing in or connecting to the internet. Editing requires online licence verification first. A previously verified editing licence can work offline for up to 24 hours, subject to its expiry. Cloud projects need a connection.

Which Structurizr files can I open?

Open a .dsl workspace to explore its supported context, container and component views. Desktop 1.0.0 supports a subset of Structurizr DSL; external includes, scripts and plugins are not supported. Keep a backup of your source files before editing.

How do I install it?

On macOS, open the DMG and drag UXXU to Applications. On Windows, run the EXE installer. On Debian or Ubuntu, install the DEB with your package manager. For AppImage, allow the downloaded file to run as a program in its file permissions, then open it.
