Tabby

Smart tab groups, zero effort.

Tabby automatically groups, hibernates, and restores your tabs. Spend less time managing your browser and more time using it. **Smart grouping** sorts your open tabs by site instantly — no dragging, no manual sorting required. **Auto-hibernation** puts inactive tabs to sleep after 30 minutes, freeing up RAM without closing anything. Tabs reload instantly when you need them. **Session restore** keeps a continuous snapshot of your tabs. Close your browser or restart your computer — everything comes back exactly as you left it. **Manual hibernate** lets you put any individual tab to sleep on demand by clicking Sleep. **Real-time search** finds any open tab instantly as you type — including hibernated ones. **Memory counter** shows exactly how much RAM Tabby has freed since you opened your browser. No account required. No data sent anywhere. Everything stays on your device.
