02 / Toolkit

Choose what goes
into your desktop.

Use the desktop preset for a complete workspace, or compose only the services and components your site needs.

Window controls

Add move, resize, minimize, and maximize controls to your own React content.

Files and storage

Keep files in memory or use a storage adapter. The desktop includes file browsing, editing, and local previews.

Apps and extensions

Register your own apps and commands. Use React components to add a dashboard or widgets behind the windows.
