Visual comparison
Drag the slider to compare unmanaged browser tabs with TabStack auto-grouping.
Clusters tabs from the same website into native, color-coded Chrome tab groups without manual drag-and-drop.
Expanding a stack keeps your current task open while collapsing dormant groups to preserve horizontal tab space.
Uses Chromium's native tab discard API to free memory from idle tabs without closing them or losing your scroll position.
Core features
Scroll down to see the workflow in action.
Multiple scattered tabs from YouTube, Amazon, and Spotify collapse automatically into tidy, organized stacks.
Every website gets its own color-coded stack that expands only when you're using it and stays folded when you're not.
Background tabs automatically hibernate to free up memory, restoring instantly the moment you click back.
Zero configuration
Runs natively in Chromium with zero background overhead.
Browse normally across YouTube, GitHub, docs, and search without worrying about clutter.
Same-domain tabs stack into clean, color-coded native groups in real time.
Background groups collapse and sleep automatically, reclaiming memory used by idle pages.
Pure privacy
Built strictly on native Chromium extension APIs. No bloat, no tracking.
