Low-profile desktop pet
Install once and keep coding. Tamamon sits as a small overlay along the bottom of your desktop, above other windows, without taking focus.
Tamamon
Tamamon is a free macOS desktop pet that grows as you code with Claude, using Claude usage totals to evolve on your Mac without reading your code, files, or conversations.
Overview
Tamamon is a free macOS desktop pet that grows as you code with Claude. It appears as a small companion along the bottom of your screen and evolves in step with your Claude Code usage, turning your work sessions into a collection game with a virtual pet element.
The app is designed to stay local and lightweight. It reads only your Claude usage numbers through your existing Claude Code login, never your code or conversations, and it says nothing about your work leaves your Mac. There is no extra account, API key, or setup beyond installing the app and coding normally.
Features
Growth tied to Claude usage
Your Claude Code activity nudges the pet through egg, baby, adult, and evolved stages. Growth only moves forward, based on usage over time.
Uses Claude usage, not your code
The pet reads your live session and weekly Claude usage through your existing Claude Code login, with no separate account or API key.
Collectible creature family
Different species and evolved forms appear as you progress, and a dex screen tracks which ones you have met.
Context-aware reactions
The pet reacts when Claude is waiting on your input, and it also responds to time and weather changes such as rain or nightfall.
Simple care and customization
You can feed snacks, play with balls and bubbles, decorate the nest, and open a room where creatures walk around together.
Use cases
Daily Claude Code sessions
Use Tamamon while coding in Claude Code if you want a small companion that reflects your session activity without asking you to manage another app.
Tracking coding momentum
If you prefer visible feedback for progress, the pet’s stage changes and collection mechanics give you a lightweight way to see ongoing usage accumulate.
Light, pet-style motivation
For people who like low-stakes virtual pets, Tamamon adds feeding, play, and decoration without requiring manual dashboards or account setup.
Local-only desktop companion
If you care about keeping work local, Tamamon is positioned for Mac users who want a companion app that does not upload code, files, or conversations.
Ambient desktop interaction
If you want a desktop element that reacts to context, the pet responds to waiting periods, weather, and time of day while staying anchored at the bottom of the screen.
