psmux

The real tmux for Windows. Not a port, not a wrapper, not a workaround.

psmux is a native Windows terminal multiplexer built from the ground up in Rust. It uses Windows ConPTY directly, speaks the tmux command language, reads your .tmux.conf, and supports tmux themes. All without WSL, Cygwin, or MSYS2.

💡 Tip: psmux ships with tmux and pmux aliases. Just type tmux and it works!

👀 On Windows 👇

Installation

Using WinGet

winget install psmux

Using Cargo

cargo install psmux

This installs psmux, pmux, and tmux binaries to your Cargo bin directory.

Using Scoop

scoop bucket add psmux https://github.com/psmux/scoop-psmux
scoop install psmux

Using Chocolatey

choco install psmux

From GitHub Releases

Download the latest .zip from GitHub Releases and add to your PATH.

From Source

git clone https://github.com/psmux/psmux.git
cd psmux
cargo build --release

Built binaries:

target\release\psmux.exe
target\release\pmux.exe
target\release\tmux.exe

Docker (build environment)

A ready-made Windows container with Rust + MSVC + SSH for building psmux:

cd docker
docker build -t psmux-dev .
docker run -d --name psmux-dev -p 127.0.0.1:2222:22 -e ADMIN_PASSWORD=YourPass123! psmux-dev
ssh ContainerAdministrator@localhost -p 2222

See docker/README.md for full details.

Requirements

• Windows 10 or Windows 11
• PowerShell 7+ (recommended) or cmd.exe
  • Download PowerShell: winget install --id Microsoft.PowerShell
  • Or visit: https://aka.ms/powershell

Why psmux?

If you've used tmux on Linux/macOS and wished you had something like it on Windows, this is it. Split panes, multiple windows, session persistence, full mouse support, tmux themes, 76 commands, 126+ format variables, 53 vim copy-mode keys. Your existing .tmux.conf works. Full details: docs/features.md · docs/compatibility.md

Usage

Use psmux, pmux, or tmux — they're identical:

psmux                        # Start a new session
psmux new-session -s work    # Named session
psmux ls                     # List sessions
psmux attach -t work         # Attach to a session
psmux --help                 # Show help

Claude Code Agent Teams

psmux has first-class support for Claude Code agent teams. When Claude Code runs inside a psmux session, teammate agents automatically spawn in separate tmux panes instead of running in-process.

psmux new-session -s work    # Start a psmux session
claude                       # Run Claude Code — agent teams just work

No extra configuration needed. Full guide: docs/claude-code.md
