What is wmux?

A native terminal multiplexer for Windows. Split your terminal into panes, organize work into tabbed workspaces, and let AI agents control everything over a JSON-RPC socket — all from a single desktop app built in Rust.

Note

wmux is the Windows counterpart to cmux. Same protocol, native experience.

Get Started

Download the installer:

Download wmux.msi

Or build from source:

cargo install tauri-cli
git clone https://github.com/fernandomenuk/wmux.git
cd wmux/crates/wmux-app
cargo tauri build

Features

Graphical Split Panes — vertical and horizontal, infinitely nestable, with high-DPI support

Tabbed Workspaces — create, rename, and switch between workspaces from the sidebar

AI-First Socket API — JSON-RPC over Windows named pipes at \\.\pipe\wmux. Let Claude Code, Cursor, or Copilot control your terminals programmatically

Any Shell — PowerShell, CMD, WSL, nushell — anything that runs on Windows

Command Palette — quick actions with Ctrl+Shift+K, navigate with arrow keys or Tab

Blazing Fast — Rust + ConPTY, near-zero overhead, no Electron

Claude Code Integration

wmux ships with a built-in MCP server. One-click setup from within the app:

1. Open wmux
2. Press Ctrl+Shift+K → select "Connect to Claude Code"
3. Restart Claude Code

That's it. Claude Code can now create workspaces, split panes, run commands, and read terminal output — all through wmux.

Socket API

AI agents connect over a named pipe and control your terminal sessions with JSON-RPC.

$pipe = New-Object System.IO.Pipes.NamedPipeClientStream(".", "wmux", [System.IO.Pipes.PipeDirection]::InOut)
$pipe.Connect(5000)

Method	Description
workspace.create	Create a new tabbed workspace
workspace.list	List all workspaces
surface.split	Split the current pane
surface.send_text	Send commands to a terminal
surface.read_output	Read terminal screen content
surface.send_key	Send keys (Enter, Ctrl+C, etc.)
