Users switch between apps constantly — hundreds of times a day. Windows Alt+Tab hasn't changed in any meaningful way since the 1990s. It doesn't know about browser tabs, it always seems to appear on the wrong monitor, and it shows windows in an order that makes no sense for modern multitasking workflows.

​

Tabber is a complete replacement. App windows are grouped. Every browser tab in Chrome and Edge appears as an individual window. Windows are sorted by most-recently-used order, so the one you want is almost always in the first or second position. On multi-monitor setups, the UI opens on every screen. A launch-to-monitor feature lets you decide which screen a window lands on before you activate it.

​

Tabber is built for power users, developers, and knowledge workers who manage many windows and browser tabs simultaneously. It works on Windows 10 and 11.
