Tabby
Tame your tabs.
Free your memory.
Tabby closes duplicate tabs, searches every window at once, and quietly suspends the tabs you're not using — so your browser stays fast.
Everything you need to manage tabs
Powerful where it counts, invisible the rest of the time.
Close duplicate tabs
Clear duplicates with one click — or let Tabby auto-close them the moment they appear.
Search every window
Find any open tab across all your windows and jump straight to it. No more hunting.
Memory saver
Auto-suspend tabs idle past your threshold using Chrome's native discard — they reload on click.
Smart exceptions
Never suspends pinned tabs, tabs playing audio, or hostnames on your personal allowlist.
Tab-count badge
See how many tabs you have open at a glance, right on the toolbar icon. Optional.
Featherweight
Vanilla JS, no framework, no build step, event-driven service worker. It stays out of your way.
Private by design
Tabby needs just three permissions — and never reads your page content.
tabs
To list, switch, close, and discard your tabs. This is the core of what Tabby does.
storage
To sync your settings and track last-active time — kept in session storage, never on disk.
alarms
To run a lightweight once-a-minute sweep that finds tabs idle long enough to suspend.
- ✓No backend. Nothing you do ever leaves your browser.
