What is PeonPing?

PeonPing is a free, open source notification system for developers working with AI coding agents. It plays a voice line, plays a sound, and shows a desktop notification the moment Claude Code, Cursor, Codex, or another agent finishes a task or needs your approval. The result is that you can let the agent work and come back when it actually calls for you.

The character is its real personality. PeonPing ships with over 160 sound packs across 14 languages featuring voice lines from Warcraft III, StarCraft, Red Alert 2, Team Fortress 2, and many others. There is also an MCP server so agents can pick their own sound effects, a desktop pet orc for macOS, and an optional Peon Trainer that reminds you to do pushups during long sessions.

What Are PeonPing’s Key Features?

Multi Agent Hooks

Built-in support for Claude Code, Cursor, Codex, Kiro, Antigravity, and most major AI coding tools. Configuration is hook based, so once it is wired up to your terminal or IDE, every agent run produces the appropriate audio cue without manual intervention.

Sound Pack Library

Over 160 character packs across 14 languages give you Warcraft, StarCraft, GLaDOS, TF2, and dozens of other voice line collections. Packs are distributed through GitHub, so you can install community packs or publish your own. No repeated lines from the same category play in a row.

Event Specific Audio

Different sounds fire for task completion, errors, approval prompts, and limit hits. You can tell by ear whether the agent finished cleanly or is waiting on you, without switching back to the window every few minutes.

MCP Server Integration

An optional MCP server exposes the sound system to the agent itself, so the model can choose contextually appropriate effects mid-conversation. A successful build can trigger a cheer, an error can trigger something more apologetic.

Terminal Tab Indicators

Project status surfaces in terminal tab titles with completion icons, useful when you have multiple parallel agent sessions across different repos. You can glance at your tabs and see which ones are blocked, finished, or still running.

Peon Trainer and Desktop Pet

Optional v2.0 features include a 300 daily pushup and squat tracker with session reminders, plus an animated orc tamagotchi on macOS that reacts to coding events. Pure novelty, but oddly motivating during long sessions.
