xmux

A graphical tmux for macOS — multiple terminal panels in one window, resizable and repositionable via drag-and-drop.

Features

• Multiple panels — split any panel horizontally or vertically, infinitely
• Drag-and-drop — grab a panel by its header and drop it into any edge or center of another panel to reorder
• Border resize — drag the divider between panels to resize
• Multiple tabs — independent layouts per tab, like tmux windows
• Tokyo Night theme — consistent dark theme across UI and terminal
• Native macOS feel — hidden title bar with traffic lights, native PTY via node-pty
