Attyx

Attyx is a terminal emulator designed for running, watching and coordinating AI coding agents from one window. It is GPU accelerated, written in Zig with Metal and OpenGL rendering, weighs under 5 MB and runs on macOS on Apple Silicon and Intel and on Linux for x64 and ARM64. It installs through Homebrew. It is for developers who run several agents at once. A full screen agent dashboard shows every agent across all sessions with its state, token counts, cost and context window usage, live, and lets the user jump to, zoom or close any pane. Attyx reads the lifecycle of Claude, Codex, opencode and pi.dev and marks each pane as working, waiting for input or idle, so it is clear which agent needs attention. Every pane has a stable ID, and over a Unix socket one agent can spawn panes, send keystrokes and read output from another; the same controls are available through the attyx command line tool and to any MCP client through a built in MCP server. Splits, tabs and floating popups are built in, sessions are backed by a daemon so layouts survive closing the window, a command palette searches every action, and twenty two themes ship with support for custom TOML themes. Attyx is free and open source under the MIT license, and no paid plans are listed. It is published by Semos Labs, and the source is on GitHub.
