A desktop pet that lives with you and grows alongside your AI work — every prompt is XP, every level a new form. 🥚→🦄🐒🦍
petpet is a desktop companion app that turns real AI coding work into a growing virtual pet. The app quietly monitors your usage of AI coding tools (Claude Code, Codex, OpenCode, and Aider) running on your machine. Every time you use these tools, your pet earns experience points automatically. Your pet evolves through 10 visual stages from egg to final form, with celebratory animations at each evolution. The app is fully local—no data ever leaves your computer—and is free and open source. You can raise multiple pets, switch between them, create custom templates with your own artwork, and export pets as files to share with friends. The dashboard shows your lifetime AI spending, per-model breakdowns, and a history of every XP gain.
How It Works
A friend tells you about an app that turns your AI coding sessions into a companion that evolves as you work harder.
The app works on Mac, Windows, or Linux. You drag it to your Applications folder and open it for the first time.
Three difficulty levels are offered: Easy (Unicorn), Medium (Sun), or Hard (KingKong). You select one and give your new pet a name.
The app quietly watches your coding sessions in the background. Every time you use Claude Code, Codex, OpenCode, or Aider, your pet feels it.
When your AI assistant finishes a task, your pet briefly shows a happy animation and gains experience points automatically.
Over time, your pet transforms from an egg into new forms. Each evolution brings a visual celebration and a stronger appearance.
Raise a whole menagerie and switch which one is your active companion whenever you like.
Design custom difficulty curves, evolution stages, and even draw your own sprites for a unique companion.
Export your fully-grown companion and send it to a friend, who can import it and continue raising the same pet on their own machine.
