vmux — Agent-Friendly Terminal Extension for VS Code

[](https://marketplace.visualstudio.com/items?itemName=roboco-io.vmux) [](LICENSE)

[English](README.md) | [한국어](README.ko.md) | [日本語](README.ja.md)

VS Code terminal extension for AI coding agents such as Claude Code, Codex, and Gemini CLI. Agents can send notifications, manage sessions, display metadata, and orchestrate multi-terminal workflows — all from the terminal.

Inspired by [cmux](https://github.com/manaflow-ai/cmux), a native agent terminal for macOS.

Install

# From VS Code Marketplace
code --install-extension roboco-io.vmux

# Or search "vmux" in the VS Code Extensions panel

Features

Notifications

Send notifications from agents to VS Code — Status Bar badge, sidebar TreeView, and system popups.

vmux notify --title "Claude Code" --body "Task complete"
vmux notify --title "Build" --body "Failed" --level error

Terminal Control

Create, focus, send commands to, and close terminals programmatically.

vmux create-terminal --name "agent-1" --cwd /project
vmux send --terminal "agent-1" "npm test"
vmux focus --terminal "agent-1"
vmux close --terminal "agent-1"

Session Management

Save and restore named terminal layouts, including split groups.

vmux save-session --name "dev-setup"
vmux restore-session --name "dev-setup"

Metadata Panel

Display per-terminal status pills, progress bars, and structured logs in the sidebar.

vmux set-status build passing --icon check
vmux set-progress 0.75 --label "Testing..."
vmux log "All tests passed" --level success

Multi-Agent Grid

Launch NxM split terminal grids and broadcast commands to all of them.

vmux broadcast --grid agents "git pull && npm test"
