Running multiple AI coding agents simultaneously is increasingly common. Claude Code, Codex, and Gemini CLI can all run in parallel on different tasks — but keeping track of which one is working, which is waiting for input, and which has finished requires constant attention. AgentPet solves this with a macOS menu bar app and a charming desktop pet that gives you an ambient, at-a-glance signal for all your running agents.
AgentPet is a native macOS application developed by Nguyễn Thành Đạt (@ntd4996) on GitHub. It runs as a menu bar app and displays a small animated pet on your desktop that reacts to AI coding agent activity. The pet’s behaviour changes based on whether your agents are working, waiting for input, or idle — giving you a peripheral signal you can read without breaking focus on your work.
The application is built with Swift and SwiftUI, uses a Unix-socket daemon for agent events, and includes a tiny CLI helper for registering agents.
AgentPet monitors multiple AI coding agents simultaneously — Claude Code, Codex, and Gemini CLI are all supported. You can run four or five agents in parallel and know at a glance which are active and which need your attention.
A small animated pet floats on your desktop and reacts to agent activity. The pet’s animation changes based on the agents’ collective state — busy, idle, or waiting for input. It is a peripheral signal that does not require you to look at a specific window or dashboard.
The menu bar component gives you quick access to agent status without the pet being visible. You can see which agents are running and their states from a dropdown.
Built entirely in Swift with SwiftUI, AgentPet is a proper native macOS application with appropriate performance characteristics and system integration.
The agent event system uses Unix sockets, which means communication between the CLI helper and the desktop app is fast and low-overhead.
AgentPet is for macOS developers who run multiple AI coding agents in parallel and want an ambient signal about their status without constant window switching. It is particularly useful for developers using Claude Code and Codex simultaneously on different tasks.
AgentPet is a delightful and genuinely useful tool. The desktop pet concept might sound gimmicky, but as a peripheral ambient signal for multiple concurrent AI agents it is surprisingly effective. A small, focused app that does exactly what it promises.
Rating: 8/10 — Excellent for developers running multiple AI agents on macOS. macOS-only and pet aesthetic may not suit all.
