**Agent Workflow Multiplexer Terminal** — *Go with the agents' flow.*

[Website](https://flowmux.org/) · [Latest release](https://github.com/flowmux-ai/flowmux/releases/latest)

A terminal for AI agent workflows, browser control, and task signals.

flowmux is a Linux/GTK4 terminal for AI coding agents. The terminal pane uses the system VTE widget for terminal emulation, flowmux-owned PTYs, and GTK integration. Supported on Ubuntu 24.04 and later.

Unofficial GPL-3.0-or-later reimplementation inspired by [cmux](https://cmux.com/ko), a macOS/AppKit app. Not affiliated with cmux.

Install (Ubuntu 24.04+, amd64)

curl -fsSL https://flowmux.org/install.sh | sh

Uninstall the release package with `sudo apt remove flowmux`.

Control internal browser

A WebKitGTK 6.0 browser tab lives next to terminal tabs in the same pane tree. The clip shows an AI agent driving the page over flowmux's IPC socket — snapshot the DOM, click, type, read state back — with no system Chromium and no separate driver.

AI Agent notification (Claude, Codex, OpenCode, Gemini, Antigravity)

`flowmux fix` adds lifecycle hooks to Claude Code, Codex, OpenCode, Gemini, and Antigravity. FlowMux keeps session start/end separate from turn working/waiting/completion, then surfaces attention and completion as native desktop notifications — routed to the workspace that fired them, suppressed while that surface is focused, and isolated per window.

Claude's `PermissionRequest` has no tool-use ID, so FlowMux keeps a conservative permission marker for the whole model-call batch and clears it at the matching `PostToolBatch` boundary. Explicit input tools are still correlated by their tool-use IDs. Codex permission waits are scoped to the reported root or child turn and are cleared only
