Overview

Arrange the tabs of the current window evenly across the screen by a chosen split count.

Stop dragging and resizing windows by hand. FlexSplit arranges your browser windows into a clean, even grid across the screen — in a single click. Features • One-click split — choose 2, 3, 4, 5, 6, or MAX. Each option is a live preview of the layout it creates. • MAX — tile as many windows as you have open tabs (up to 10). • Merge back — gather scattered windows into one maximized window with a single button. The perfect undo for a split. • Pick your scope — tile only the active monitor, only the active browser window, or every window across all monitors. • Edge-to-edge fit — the last column absorbs leftover pixels and an adjustable border compensation keeps gaps minimal on Windows. • English & Japanese — the interface follows your browser language automatically. How to use Click the FlexSplit toolbar icon. Pick a scope (Active monitor / Active browser / All windows). Click a layout (2–6 or MAX) to tile instantly — or "Merge into one" to gather. Privacy FlexSplit does not collect, store, or transmit any data. It only uses the tabs and windows permissions to read tab/window positions and move and resize your windows on your own machine.
