Tamamon: A macOS desktop pet that evolves based on your Claude Code activity
By
Jason Jeong
Summary
Tamamon is a macOS desktop pet created by a solo developer that lives on top of your screen and grows as you code with Claude Code. Starting as an egg, it evolves based on token-based coding activity. Features include 20 collectible species via weekly gacha, feeding and play mechanics, real-time weather and time reactivity, and a local-only design with no accounts, sign-ins, or data tracking.
