iCloud Tab Data

Your iCloud shared tab data is saved in a sqlite database on your computer.

While it used to live in ~/Library/Safari/CloudTabs.db, it now lives at ~/Library/Containers/com.apple.Safari/Data/Library/Safari/CloudTabs.db (a lot of things have moved to ~/Library/Containers over the years to wall them off from the rest of the system without permission)

All the Tabs One Liner

sqlite3 ~/Library/Containers/com.apple.Safari/Data/Library/Safari/CloudTabs.db 'select url from cloud_tabs'
