TabKeeper – Tab Manager & Duplicate Cleaner

Protects tabs you're still working on. Auto-cleans the rest. Merges duplicates.

Too many tabs slow the browser. Closing the wrong one costs unfinished work. TabKeeper is a tab manager built around one idea: pin as active work. Mark tabs you're still using; TabKeeper will not auto-archive them and will not close them when cleaning duplicate tabs. Idle clutter gets auto-archived into a restorable list after a timeout you control. That's the difference from tools that only close by idle time or dump every tab into one pile. Use it as a duplicate cleaner too — merge same-URL tabs in one click while pinned work stays open. Settings stay on your device. • Pin any tab as active work (protected from auto-archive and duplicate merge) • Auto-archive idle tabs into a restorable list (default 45 minutes; configurable) • Close duplicate tabs without touching pinned work • Search, restore one, or restore all from the archive • Options: idle timeout, excluded domains, duplicate URL matching rules • Keyboard shortcut to toggle pin (Alt+P; changeable in Chrome's shortcut settings) 100% local, no account, no data collected.
