Automatic Domain Grouping

Clusters tabs from the same website into native, color-coded Chrome tab groups without manual drag-and-drop.

Single-Stack Focus

Expanding a stack keeps your current task open while collapsing dormant groups to preserve horizontal tab space.

Native Tab Suspension

Uses Chromium's native tab discard API to free memory from idle tabs without closing them or losing your scroll position.

Core features

How TabStack organizes your browser.

Scroll down to see the workflow in action.

01

Collapse tabs into stacks

Multiple scattered tabs from YouTube, Amazon, and Spotify collapse automatically into tidy, organized stacks.

02

Domain-specific grouping

Every website gets its own color-coded stack that expands only when you're using it and stays folded when you're not.

03

RAM Saver puts tabs to sleep

Background tabs automatically hibernate to free up memory, restoring instantly the moment you click back.

04

Closed the wrong window? Get it back

TabStack saves every window the moment it closes and takes periodic snapshots. One click reopens all the tabs with their stacks, colors, and pins intact.
