WhatsApp desktop app
Multiple WhatsApp accounts in one window
Open several WhatsApp numbers together without mixing sessions: every tab is its own account, with split screen and unread alerts.
Who is it for?
Support teams answering from more than one number
Stores and companies with multiple WhatsApp lines
Agencies managing client accounts
Sales teams following several chats at once
Isolated sessions per number
Each tab is a fully separate WhatsApp account
Multiple accounts, no mixing
Every tab uses its own persisted session, so each WhatsApp number stays logged in independently.
Add a new tab
The + button opens a new WhatsApp session immediately for another number.
Close and clear the session
Closing a tab wipes that tab’s session data so old accounts do not linger on the machine.
Rename tabs
Double-click a tab name to label it by team, staff, or line number.
Drag-and-drop order
Reorder tabs by dragging them to match your workflow.
Restore tabs after restart
Tab names and order are saved and restored when you reopen the app.
Split screen
Watch more than one WhatsApp at the same time
Two-window view
Split the screen into two WhatsApp panes for the first two tabs.
Four-window view
A 2×2 grid of the first four tabs for peak-hour monitoring.
Expand one pane
Maximize any pane to fill the screen, then restore the split in one click.
Layout-aware zoom
Zoom adjusts automatically so chats stay readable in split mode.
Unread alerts
See which account needs a reply without switching
Red badge on the tab
The app reads WhatsApp’s unread count from the page title and shows a red dot on that tab.

WhatsApp can request desktop notifications so urgent chats are not missed.
