## What it is
psmux is a native Windows terminal multiplexer written in Rust that implements the tmux command language, reads .tmux.conf, and uses Windows ConPTY directly without WSL or Cygwin. It ships as psmux, pmux, and tmux commands with mouse support, tmux themes, and 90+ commands.

## Use cases
- use tmux on windows without wsl
- split terminal panes in powershell
- terminal multiplexer for windows terminal
- run tmux sessions in cmd.exe
- detach and reattach terminal sessions on windows
- tmux alternative for windows
- share tmux config and themes on windows

## When to choose
- you want tmux-style session and pane management natively on Windows
- you use PowerShell, Windows Terminal, or cmd.exe and miss tmux
- you want tmux config/theme compatibility without WSL, Cygwin, or MSYS2

## When to avoid
- you are on Linux or macOS, where real tmux is available
- you need full tmux feature parity or tmux plugins that psmux does not implement
- you rely on ecosystem tooling built specifically for POSIX tmux
