Attyx
GPU-accelerated terminal for agentic workflows with native MCP support
If you live in the terminal and run multiple AI agents daily, Attyx is the most purpose-built tool for the job. It's free, lightweight, and deeply integrated with the MCP ecosystem. However, it's not a general-purpose replacement for iTerm2 or tmux — its strength is its agent-first design.
- Developers running multiple AI coding agents simultaneously
- Agent workflow orchestrators needing to coordinate agents within a terminal
- Power users who want a fast, GPU-accelerated terminal with deep scriptability
- Developers building custom agent pipelines that interact with the terminal environment
- Users seeking a simple, beginner-friendly terminal emulator
- Those who rely on extensive plugin ecosystems (e.g., tmux, iTerm2 plugins)
- Windows users (only macOS and Linux are supported)

About Attyx
Attyx is a GPU-accelerated terminal built specifically for the agentic era. It is agent-aware end to end: it tracks the lifecycle of AI coding agents (Claude Code, Codex, opencode, pi.dev) and paints a status dot on every pane — idle, working, or waiting on you. It exposes a full IPC layer, the attyx CLI, and a native MCP server so agents and scripts can spawn, read, and drive panes, and coordinate one another. Written in Zig and under 5 MB, it offers persistent sessions, splits, tabs, popups, and a command palette — all in a single binary. Attyx is designed for developers who work heavily with AI agents and need a terminal that can orchestrate them. It provides a dashboard view of all agents, their tokens, cost, and context window live. The terminal is scriptable over Unix sockets, CLI, and MCP, allowing agents to control each other. It also features deterministic VT compatibility, GPU-accelerated rendering (Metal on macOS, OpenGL on Linux), and 22 built-in themes. What makes Attyx different is its deep integration with the agent workflow. It detects agents and shows their state; it exposes every pane, tab, and keystroke as MCP tools; and it provides a Claude Code skill for native control. The terminal is lightweight, fast, and focuses on making the agent developer's experience seamless. Attyx is free and open-source under the MIT License. It runs on macOS (Apple Silicon & Intel) and Linux (x64 & ARM64).
Behind the Verdict
Attyx fills a gap no other terminal addresses: agent orchestration. If you're running Claude Code alongside Codex and opencode, Attyx gives you a single screen to monitor all their states, costs, and context windows. The IPC and MCP layers let agents control each other — something you can't do with iTerm2 or tmux out of the box. Where it shines is the dashboard, status dots, and scriptability. The dashboard is htop for agents — live token/cost per pane. The status dots are simple but effective: one glance tells you which agent is stuck waiting for input. The MCP server is a first-class citizen, not an afterthought; pointing Claude Desktop at Attyx gives it direct terminal control. When to pass: if you only use a single agent occasionally, the extra features add little value. Attyx also lacks the plugin ecosystem of iTerm2 or tmux — no tmuxinator, no custom scripts without the CLI. Windows support is absent. And you need to be comfortable with TOML configuration and CLI workflows. Compared to alternatives: Warp is also GPU-accelerated and AI-augmented, but Warp focuses on human command completion and AI suggestions, not agent coordination. iTerm2 and tmux are mature but have no concept of agent lifecycle. Attyx is the only terminal that treats agents as first-class citizens. Caveats: it's still early (v0.4.12 as of writing). Some features are in flux, and documentation could be richer. But it's MIT-licensed and under active development — a safe bet for early adopters.

Models Under the Hood
Limitations
- Attyx is currently in early development (v0.4.12).
- It runs only on macOS and Linux — no Windows support.
- The agent detection works with specific agents (Claude Code, Codex, opencode, pi.dev) and may not recognize others.
- While the binary is under 5 MB, GPU acceleration is limited to Metal (macOS) and OpenGL (Linux).
- There is no web-based or mobile version.
