SigmaOSUnderrated
A keyboard-first Mac browser organized around workspaces and split views.

Best for
Mac users who treat browsing as task management and want to work without a mouse.
Why it deserves attention
SigmaOS groups pages into workspaces, opens several pages in split view, and exposes most actions through keyboard shortcuts and a command bar. Its Airis assistant summarizes and compares pages, and the task-oriented model reduces tab clutter. It is Mac-only, newer than mainstream browsers, and the paid tiers matter if you want the AI features.
