Broadcast Channel API
Checking compatibility...
Communicate between different browsing contexts (windows, tabs, iframes) using the Broadcast Channel API. Perfect for synchronizing state or sending messages across tabs.
The Broadcast Channel API requires multiple tabs or windows to be open for communication. Messages are only received by contexts that are actively listening on the same channel name.
