Primary and secondary sync
Perform an action in the primary window and selected secondary windows repeat it in order.
Window sync
Work in one window and mirror actions to the rest
Select browser windows and mirror page actions across profiles to reduce repetitive clicks.
Central control for multi-window actions and layout
Window sync runs in the desktop app with clear primary, secondary, and runtime status.
Window selection & status
View running profiles and choose the primary and secondary windows for sync.
Multi-screen grid layout
Choose a display and arrange all synced windows into a grid automatically.
Pause and resume anytime
Start, pause, or refresh sync and restore windows to their original positions.
Window selection, action sync, and desktop layout in one controller
The sync controller reads active profile windows, builds a primary-and-follower group, then controls both mirrored actions and window placement.
Window management
See every active window clearly before building a sync group
Active windows from the current team appear in one controller, where the list and selected sync range can be refreshed at any time.
Active window list
Show the profile sessions and window states that can join the current sync.
Multi-window selection
Choose at least two windows for a sync session while all other windows remain independent.
Primary window
Choose one selected window as the primary and use the rest as followers.
Start and pause
Keep the not-started, running, or unavailable state visible with direct start and pause controls.
Session refresh
Refresh after profiles open or close so the available window list stays accurate.
Sync and layout
Control mirrored actions and window layout separately, then restore the workspace
Teams can mirror only the web actions they need, arrange selected windows on a display, and restore their original positions afterward.
Action types
Control clicks, input, scrolling, tabs, and other supported page actions separately.
Cursor feedback
Show the synced cursor when needed so execution locations are easier to verify.
Target display
Read connected displays and choose the screen used for the current arrangement.
Automatic grid layout
Calculate a layout from the window count so all selected profiles stay visible.
Restore positions
Return selected windows to their previous positions when the sync work is done.
Use window sync
Open the profiles you need, then choose the primary and secondary windows.
Open multiple profiles
Launch the browser projects that need the same task.
Select synced windows
Choose one primary window and select the secondary windows that should follow it.
