WHY VERTICAL TABS
Why Vertical Tabs Change Everything
Horizontal tab bars were designed for a handful of pages. Modern work demands dozens. Vertical tabs give every page a readable name and a logical home.
Titles you can actually read
Vertical space means full page titles stay visible, so you never confuse two similar tabs again.
Room for dozens of tabs
A sidebar scrolls naturally, while a horizontal bar squishes tabs into unreadable favicons.
Context at a glance
Group work, research, and personal tabs visually. Switch mental modes without losing your place.

Let Agent Mode compile a report across dozens of sources while you keep writing in your main workspace.
Automate forms across internal tools

FAQ
Common questions about browsers with vertical tabs

Why should I use vertical tabs instead of horizontal tabs?+
Vertical tabs use screen space more efficiently on wide monitors, keep full page titles visible, and reduce the visual clutter that comes from a crowded horizontal tab bar.
