About TabZen
TabZen keeps tab sprawl under control by tracking how you actually use your tabs
— then giving you fast, reversible ways to clean up.
━━ WHAT IT DOES ━━
USAGE TRACKING
TabZen records when each tab was opened, when you last used it, and how often
it is genuinely used. "Used" means real engagement: you stayed on the page past
a dwell threshold, or you interacted with it (mouse, scroll, keys, selection).
A cooldown keeps a tab you work in all afternoon from drowning out one you
return to every day.
DUPLICATE HANDLING — BEFORE THE PAGE LOADS
When you open a page that is already open, TabZen can catch it *before* the
duplicate is fetched and ask what you want:
• Switch to the tab that already has it
• Open it here anyway
For a tab navigating away from a page you were reading, it also offers to switch
and return that tab to where you were — so you do not lose your place.
Or skip the question entirely: switch silently, or move the existing tab next to
whatever spawned the duplicate.
TIDY UP IN ONE CLICK
• Close duplicates
• Group or close stale tabs — old tabs you never actually read
• Close every tab from a site, with subdomains grouped or separated
(mail.google.com and chat.google.com, together or apart — your choice)
Everything TabZen closes goes to a Recently Closed list you can restore from.
ORGANIZE
Sort by title, domain, when opened, or when last used. Merge every window into
one, split a window by site, or auto-group by domain with a stable colour per
site.
MOST VISITED
See which sites you actually use over the last 7 or 30 days, ranked by real
visits rather than by how many tabs happen to be open, with a drill-down to the
individual pages.
━━ PRIVACY ━━
TabZen makes no network requests. None. Every byte it records stays in your
browser profile, and Options → Your data deletes all of it in one click.
Page access is optional and off by default — TabZen works without it, measuring
foreground time instead of interaction, and asking about duplicates with its own
page and desktop notifications. Turn it on only if you want activity tracking.
━━ CONTROL ━━
• A pause switch stops everything automatically, without uninstalling
• Duplicate matching strictness is configurable, including which sites use
#fragments for routing and which sites to never deduplicate
• Pinned tabs, audible tabs and grouped tabs are protected from purging by
default
• Tabs restored from a previous session are never purged on age alone, since
Chrome does not report their real age
• Dry-run mode logs what would close without closing anything
