ShiftPlus captures the whole working setup, not just the windows: which apps are open, which browser profile each one uses, where windows sit and which macOS Space each app belongs to, then rebuilds it on demand.

A lifetime Pro licence is $14.40 for one Mac and $23.40 for two Macs with iCloud sync, down from $24 and $39, paid once.
Restoring a saved workspace switches Spaces and relaunches each app on the right one across multiple displays, including browser profiles and terminal environments.
It is a native app of about 11 MB for macOS 14.6 and later, with a 14-day trial, optional iCloud sync and a Raycast extension that switches workspaces from the launcher.

Workspace contents stay on the Mac, and the optional analytics are off by default.
