How it works

How Moose works

Moose keeps your essential sites visible side-by-side, so focus stays on the work instead of tabs. Change the layout, rearrange your websites, configure everything once.

Moose Browser
Switch between predefined layouts—focus on one site or see them all. Pick what fits the moment. You can drag tiles to change order—try moving the second tile to first.
Keep only what matters. Four tiles by default, expandable. Opening a new site closes the oldest, but you can always undo. You can drag tiles to change order—try moving the second tile to first.
Use Profiles to isolate work and personal spaces—sign in to work and personal Gmail at the same time. You can drag tiles to change order—try moving the second tile to first.
New website
Opening a new website will close the last tile. You can drag tiles to change order—try moving the second tile to first.
