What psmux is
psmux is a free, native Windows terminal multiplexer built in Rust using Windows ConPTY. It provides persistent local sessions, split panes, multiple windows, and five layouts for organizing terminal work. It reads existing .tmux.conf files and offers more than 90 tmux-compatible commands. Mouse support handles pane selection and resizing, while vim-style copy mode provides 53 key bindings. It supports tmux themes, 256 indexed colors, and 24-bit true color. Panes can run PowerShell, cmd.exe, Git Bash, WSL, nushell, and other Windows executables. The project describes libtmux compatibility, with a Windows encoding caveat, and documents examples for Python, PowerShell, Node.js, Go, and Rust. Claude Code agent teams can spawn teammates in visible panes. Installation options include WinGet, Cargo, Scoop, Chocolatey, GitHub release downloads, and building from source. It requires Windows 10 or 11 and lists Windows Terminal, conhost, VS Code terminal, and other ConPTY hosts as supported terminals.
