Your tabs, filed into spaces.

TabZen turns a pile of open tabs into a set of named spaces. Save a space in one click, restore it later exactly as you left it. Drag to reorder, and hit ⌘K for a command palette that lets you run the whole extension without touching the mouse.

I built it because every tab manager I tried either shipped my browsing data to a server or hid the useful parts behind money. TabZen does neither.

Five permissions, zero host access, fonts bundled inside, and it never makes a network request. Uninstall it and the data leaves with it, because there is no server it could have been left on.

Spaces and sessions. Save the tabs you have open into a named space and bring the whole set back in one click.

Command palette. Hit ⌘K, search any space or action, jump straight there.

Tab sleep. Tabs you are not using go to sleep, so a heavy session stops eating memory in the background.

Sorting and duplicate merge. Tabs sort by domain and duplicates collapse, so the same page never sits open five times.

Archive and stats. Old spaces go to an archive instead of getting deleted. The stats view shows how tabs and sessions pile up over time.

Seven colour themes. Small thing, but you stare at it all day.
