wemux is a shell script that adds multi-user collaboration features on top of tmux. Tmux is a tool that lets you keep a terminal session running on a server and reconnect to it later, or split your terminal into multiple panes. wemux takes that further by letting multiple people share the same session over SSH, each with a different level of control. There are three ways a second person (the client) can join: Mirror Mode gives them a read-only view so they can watch the host work, Pair Mode gives them a shared cursor so both people control the same terminal together, and Rogue Mode lets the client move around to different windows independently while still being in the same tmux session. The host can kick users, see who is connected, and run multiple independent servers on the same machine if needed. Installation is straightforward. On macOS it can be installed through Homebrew or MacPorts with one command. On other systems you clone the repository, put the script somewhere on your path, copy the example config file, and add your username to the host list. Anyone in the host list can start servers, everyone else automatically becomes a client when they run wemux. The config file controls optional features like whether clients can switch between servers, whether the user list is shown, and what mode clients land in by default. The user list can also appear in your tmux status bar so the host always sees who is connected. wemux passes any commands it does not recognize directly to tmux with the right socket settings, so you can use it as a drop-in wrapper for tmux commands. The project is a single Shell script and requires tmux version 1.6 or higher.
