agentpet

Run several coding agents at once (Claude Code, Codex, ...) and AgentPet tells you, at a glance, which one is working, which one is done, and which one is waiting for your input, so you stop tab-hunting across terminals. A little pet floats on your desktop and reacts to it all.

Why

Running multiple agents in parallel means constantly switching windows to check who needs you. AgentPet surfaces that in two places:

• Menu bar monitor for the details: every running agent, its state, what it's doing, and a live timer.
• Desktop pet for an ambient signal you can read without breaking focus.

Features

• Multi-agent monitor in the menu bar: live list of every agent with a colored status dot, the project, what it's doing (running tool / waiting reason), and a per-state timer that counts in real time.
• At-a-glance menu bar icon: shows the number of running agents, and turns orange with a count when one needs your input.
• Desktop pet that reacts to the aggregate state (working / waiting / done / celebrate), with an optional chat bubble (built-in or fully custom messages).
• Native notifications when an agent finishes or needs input.
• Claude Code, Codex, Gemini CLI, Cursor, opencode, Windsurf & Antigravity integration via hooks, with one-tap install from Settings (precise working / waiting / done / idle, including "needs your input"). GLM (Z.AI) works through Claude Code automatically. Cursor, Windsurf and Antigravity report working/done (they have no "needs input" hook).
• Universal wrapper agentpet run -- <command> to monitor any CLI agent (working/done), no per-agent setup.
• Pet system: browse an online pet library and download with one click, map each animation to a state, resize, and customise chat lines.
• Polished, native Settings (tabbed, dark) that never steals focus.

Screenshots

Requirements

• macOS 13 Ventura or later (macOS 14 Sonoma+ recommended; the keyboard-focus-ring cleanup uses APIs available on macOS 14+).
• Apple Silicon (M1/M2/M3/M4) and Intel Macs are both supported.
• macOS only, by design. There is no Windows or Linux version.
• To build from source: Xcode 16 / Swift 6.

Install

Homebrew

brew install --cask ntd4996/tap/agentpet

Direct download

Grab the latest AgentPet.dmg from Releases, open it, and drag AgentPet to Applications.

Build from source

git clone https://github.com/ntd4996/agentpet.git
cd agentpet
./scripts/build-app.sh release
open build/AgentPet.app

Builds are Developer ID-signed and notarized by Apple, so they open without a Gatekeeper warning. AgentPet also updates itself: it checks for new versions automatically, and you can update in-app from the menu bar Updates button.

On first launch, open Settings → General and click Install next to Claude Code, then Enable notifications.

Uninstall

1. In Settings → General, click Remove next to each agent you connected (this strips AgentPet's hooks from the agents' config so they don't error after the app is gone).
2. Remove the app and its data:

brew uninstall --cask agentpet          # or drag /Applications/AgentPet.app to Trash
rm -rf ~/.agentpet                       # downloaded pets + state
rm -f  ~/Library/Preferences/com.agentpet.app.plist

Usage

Claude Code (recommended): install the hook from Settings. AgentPet then reflects each session's real state (including "waiting for input").

Any other CLI agent: wrap it.

agentpet run -- <your-agent-command>     # e.g. agentpet run -- aider

The session shows as working while it runs and done when it exits.

Pets

Pets use the open Codex pet-pack format (pet.json + an 8×9 spritesheet). You can:

• Browse the online library and download a pet with one click (Settings → Pet → Browse pets).
• Map animations: pick which sheet animation plays for each state.
• Delete pets you no longer want.

A starter pet is installed automatically on first launch. AgentPet bundles no pet art; packs are added at runtime.

Roadmap

• Notarized DMG + Homebrew cask
• Click an agent to reveal its terminal
• Per-project pets

Community ports

AgentPet is macOS-only, but the community has reimagined it for other platforms:

• Linux (Rust + GTK4) , agentpet-linux by @tranhuuhuy297. An independent, from-scratch port for Ubuntu (Claude Code + Codex).

These are separate community projects, not maintained here. Building one? Open an issue and we'll link it.

Tech

Swift + SwiftUI, a Unix-socket daemon for agent events, and a tiny CLI helper, all in one SwiftPM package. See docs/specs for the design.
