Collaboration¶

ThinkERD supports real-time collaboration where multiple users can simultaneously edit the same diagram. Changes are instantly synchronized, and even concurrent edits to the same element are automatically merged without conflicts.

Sync Modes¶

ThinkERD automatically switches between two synchronization modes depending on the situation. Users don't need to manually select a mode.

stateDiagram-v2
    [*] --> Solo : Open diagram
    Solo --> Live : Another user joins
    Live --> Solo : Alone for 60s
    Solo --> [*] : Close diagram
    Live --> [*] : Close diagram

    state Solo {
        [*] --> AutoSave
        AutoSave : Auto-save to server
        AutoSave : Cross-tab sync
    }

    state Live {
        [*] --> Realtime
        Realtime : Real-time sync
        Realtime : Cursor/selection sharing
    }

Mode	When	Sync Method	Characteristics
Solo	Editing alone	Auto-save + offline support	Minimizes server resources while maintaining reliable saves
Live	2+ users editing	Real-time bidirectional sync	Cursor/selection sharing, conflict-free auto-merge

Mode switching is automatic

The status bar shows the current mode (Solo/Live). When another user opens the same diagram, it automatically switches to Live. When everyone leaves, it returns to Solo after 60 seconds.
