Attyx
Attyx is an agent-aware GPU terminal that watches your AI coding agents and lets scripts and MCP clients drive them.
If you keep three or four coding agents running at once, Attyx answers a question no mainstream terminal does: which pane is blocked on me, and which is quietly burning budget? Per-pane status dots and the `attyx dashboard` table are the features you miss once you've used them, and the MCP server plus Unix-socket IPC let one agent spawn, feed, and read another without a wrapper script. A sub-5 MB Zig binary that renders on Metal feels nothing like an Electron terminal. Windows holdouts and

Skip Attyx if you run a single agent now and then, work primarily on Windows, or want a GUI settings panel and a large plugin marketplace rather than a TOML file and a native binary.
The agent dashboard's cost column is an estimate derived from the agents it tracks, so treat those figures as a running indication rather than your actual provider bill.
Attyx's pricing fits teams whose volume aligns with the published tiers. Compare against the alternatives listed below for stage-specific value.

What is Attyx?
Attyx — Attyx is an agent-aware GPU terminal that watches your AI coding agents and lets scripts and MCP clients drive them. Best for Developers running several AI coding agents in parallel who lose track of which pane needs input, Anyone who wants token, cost, and context-window visibility per agent without a separate dashboard tool, Agent orchestrators who need one agent to spawn, feed, and read another over IPC or the attyx CLI. Free to use.
Attyx is a terminal emulator for people who run AI coding agents, not just shells. It reads each agent's lifecycle from the source — Claude and Codex through JSON lifecycle hooks, opencode and pi.dev through event-bus extensions — and paints a colored dot on every pane and tab: working, waiting on you, or idle. Run a swarm and you can see at a glance which one needs you. Press Cmd+Shift+A (or run `attyx dashboard`) for a full-screen, htop-style table listing every agent across every session, with state, elapsed time, tokens in and out, context-window usage, and estimated cost, live. You can focus, zoom, or close a pane without leaving the table. Underneath sits a real terminal, not a wrapper: vertical and horizontal splits, tabs, floating popups, a fuzzy command palette at Cmd+Shift+P, regex scrollback search, vim-style visual mode, inline images via the Kitty protocol, a scriptable status bar, and 22 themes including Catppuccin, Dracula, Gruvbox, Nord, and Tokyo Night with live preview. It is written in Zig and GPU-rendered on Metal (macOS) and OpenGL (Linux), shipping as a single native binary under 5 MB with no Electron or bundled browser. Sessions are daemon-backed, so you can close the window and reattach with every pane intact. The differentiator is programmability: every pane has a stable ID, an IPC layer over a Unix socket exposes panes and keystrokes, and the attyx CLI can split, send-keys, get-text, watch, and close panes. A native MCP server (stdio via `attyx mcp`, or HTTP at 127.0.0.1:7333/mcp) exposes panes, tabs, keystrokes, and agent status as typed tools to Claude Desktop, Claude Code, or any MCP client. Attyx runs on macOS (Apple Silicon and Intel) and Linux (x64 and ARM64), installs via Homebrew, and is MIT licensed by Semos Labs — positioned against generic terminals like iTerm2, Ghostty, and tmux, which show you text but know nothing about what your agents are doing.

Behind the verdict
Where Attyx earns its place is the morning you realize four agents are running and you have no idea which one is stuck. The status dots and the dashboard table turn that guesswork into a glance: state, elapsed time, tokens in and out, context-window usage, and a cost estimate, all without leaving the table. We'd reach for this when the number of agents in flight outpaces your ability to babysit tabs. The second reason to pick it is automation. Every pane has a stable ID, the attyx CLI can split, send-keys, get-text, watch, and close panes, and the MCP server hands the same tools to Claude Desktop, Claude Code, or any MCP client over stdio or loopback HTTP. If one agent needs to spawn, feed, and read another, Attyx is the substrate rather than a script you maintain. It is also just a good terminal: splits, tabs, floating popups, a fuzzy command palette, regex scrollback search, vim-style visual mode, Kitty inline images, and 22 themes with live preview. Written in Zig, GPU-rendered on Metal and OpenGL, a single native binary under 5 MB. Daemon-backed sessions survive closing the window. Where it bites: configuration lives in TOML at ~/.config/attyx/attyx.toml, so if you want a GUI settings panel, that's not here. There is no Windows build. If you rely on a large third-party plugin or theme marketplace, you'll find the built-ins capable but not endless. And if you launch one agent now and then, the agent-aware layer is overhead you won't use. The closest alternative is whatever terminal you already run — iTerm2 or Ghostty on macOS, a tmux setup on Linux — plus a separate dashboard. Those show you text; Attyx shows you agent state and lets a machine drive the terminal. For a single agent, they're plenty. For a swarm, Attyx is doing work the others don't. In practice,
Models under the hood
as of 2026-11-14
Limitations
- Agent lifecycle status detection covers four agents — Claude Code, Codex, opencode, and pi.dev — so an agent outside that list does not get a per-pane status dot.
- GPU acceleration uses Metal on macOS and OpenGL on Linux, and documented platforms are macOS (Apple Silicon and Intel) and Linux (x64 and ARM64); the scrape lists no Windows build.
- Configuration lives in ~/.config/attyx/attyx.toml, and building from source requires Zig 0.15.2 or newer.
- It is a desktop and CLI application rather than a web or mobile one, and the seed data notes that it offers neither cloud sync of sessions nor a web or mobile client.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Attyx actually fits — and what changes day-one when you adopt it.
Open three vertical splits, launch `claude` in each, and leave `attyx dashboard` open in a floating popup; the status dots flag the one pane that goes from working to waiting, and the dashboard row shows it at 82k/200k context and roughly $0.42 spent.
Outcome: You answer only the agent that actually needs you, and you catch a context window that is about to fill before the agent starts truncating its own history.
Run `id=$(attyx split v --cmd "claude -p 'run tests'")`, then loop on `attyx get-text -p $id` until the output shows the run finished, answer a prompt with `attyx send-keys -p $id "yes{Enter}"`, and clean up with `attyx split close -p $id`.
Outcome: One agent spawns, feeds, and harvests another without a bespoke pseudo-terminal library, and the same pane ID works from any script on the machine.
Add the attyx MCP server to claude_desktop_config.json as `{"command": "attyx", "args": ["mcp"]}`, then ask Claude to read the test pane, inspect its output, and send a keystroke when the deploy prompt appears.
Outcome: Claude gets typed tools for panes, tabs, keystrokes, and agent status against the terminal that is actually running, rather than a sandboxed shell.
Use cases
- Watch several Claude Code or Codex panes at once and see which one is blocked waiting on input
- Track per-agent token burn, context-window fill, and estimated cost from a single dashboard
- Have one agent spawn a pane, run a command, and read the output of another via the attyx CLI
- Point Claude Desktop or any MCP client at `attyx mcp` to drive a real running terminal
- Keep long-running agent sessions alive across window closes with daemon-backed sessions
- Script terminal interaction over the Unix-socket IPC layer for CI-style automation
- Install the Claude Code /attyx skill so Claude gets typed control of panes and keystrokes
- Lay out agent and editor panes with splits, tabs, and floating popups on a GPU-rendered terminal
Setup time & first value
How long it actually takes to get something useful out of Attyx — broken out by persona, not the marketing-page minute.
Homebrew install on macOS (`brew install semos-labs/tap/attyx --cask`) or Linux (`brew install semos-labs/tap/attyx`) gets you to a working terminal in minutes; the first worthwhile non-default step is wiring the Claude or Codex JSON lifecycle hooks and dropping the /attyx Claude Code skill with `attyx skill install`, which together take a short configuration pass in ~/.config/attyx/attyx.toml.
Switching to or from Attyx
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From tmux: replace session and split management with built-in tabs, splits, and floating popups, and rely on the background daemon to keep panes alive across window closes.
- →From a GPU terminal like kitty or WezTerm: carry over vim-style visual mode, regex scrollback search, Kitty graphics, and Kitty keyboard protocol, then add agent dots, the dashboard, and the MCP server for the parts it
- →From an Electron-based terminal: switch to the single native Zig binary under 5 MB with Metal or OpenGL rendering and no bundled browser.
- →From hand-rolled agent scripts: replace screen-scraping with `attyx watch` and a stable pane ID, or expose the terminal directly to an MCP client via `attyx mcp`.
- ↗To tmux: sessions, splits, and tabs map back, but you lose per-agent status dots, the agent dashboard, and the MCP server.
- ↗To a mainstream GPU terminal: you keep the rendering and theme work, but you give up Claude/Codex/openCode/pi.dev lifecycle detection and typed MCP control of panes.
- ↗To a GUI-configured terminal: you gain a settings panel and possibly a plugin marketplace, and you give up the TOML hot-reload config and the sub-5 MB native binary.
