AI Agent Terminal for Windows — Run Claude Code, Codex, Gemini CLI side by side with split terminals, browser automation via CDP, MCP integration, session persistence, and smart notifications

wmux — AI Agent Terminal for Windows

Run Claude Code + Codex + Gemini CLI side by side. Split terminals, browser automation, MCP integration — the only proper way to use AI agents on Windows.

Still using one terminal for your AI coding agents on Windows?

macOS has cmux — a tmux-based terminal multiplexer for AI agents.

Windows has no tmux. Without WSL, there was no way.

wmux fixes this. Native Windows terminal multiplexer + browser automation + MCP server. Your AI agent reads the terminal, controls the browser, and works autonomously.

Claude Code writes the backend on the left
Codex builds the frontend on the right
Gemini CLI runs tests at the bottom
— all on one screen, simultaneously.

Why wmux?

1. Your AI agent controls the browser — for real

Tell Claude Code "search Google for this" and it actually does it.

wmux's built-in browser connects via Chrome DevTools Protocol. Click, type, screenshot, execute JS — all done by the AI directly. Works perfectly with React controlled inputs and CJK text.

You: "Search for wmux on Google"
Gemini: browser_open → browser_snapshot → browser_fill(ref=13, "wmux") → browser_press_key("Enter")
→ Actually searches Go
