stack — tab stacks for what you're working on

Save your tabs as named stacks. Close the clutter, reopen exactly where you left off - one click.

Stack saves your browser tabs as named working sessions — and lets you restore them instantly. You're deep in research, planning a trip, or juggling three projects at once. You've got 20 tabs open and they all matter. Then something else comes up. You either pile more on top or close everything and lose your place. Stack fixes that. One keyboard shortcut saves everything as a named stack. Type the name later to bring it all back — every tab, every scroll position, right where you left off. ━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS 1. Hit ⌘⇧S (or Ctrl+Shift+S) to open the save panel 2. Name your stack — "trip-planning", "Q2-sprint", "thesis-research" 3. Your tabs are saved and the window closes 4. Open Stack anytime, type a few letters, hit enter — everything restores That's it.
