Terminal Multiplexer for Windows

Terminal Multiplexer for Windows (wtmux) lets you run many terminal sessions inside a single window and keep them alive as long as you need. Split the screen into panes to watch a build, tail logs, and edit files side by side; organize related work into named windows and sessions you can reach in a keystroke.

Because sessions run in the background, you can detach, close the terminal, and reattach later to find everything still running. If you already know tmux, familiar prefix-key commands and ~/.tmux.conf compatibility make wtmux easy to adopt.
