What is Tamamon?
Tamamon is a macOS desktop pet that lives on top of your screen and grows the more you build with Claude Code. It starts as an egg, hatches into a tiny creature, and evolves through multiple stages as you code. With 20 species to collect through a weekly gacha system, each with its own evolved forms and unique quirks, Tamamon turns your development workflow into a cozy, gamified companion experience.
Who it's for
- Claude Code power users — who want a playful, visual reward for their daily coding sessions without leaving their terminal
- macOS desktop enthusiasts — who enjoy lightweight, always-on-top companions that react to real time, weather, and their workspace activity
- Privacy-conscious developers — who need a tool that reads only Claude usage numbers, never code or conversations, and keeps everything local on their Mac
Key features
Grows with your coding activity
Your Claude Code usage quietly feeds the egg, nudging it through stages from egg to baby, adult, and evolved forms. Neglect it and it sulks; care for it and it beams — all without any account, API key, or setup.
A growing crew of collectible species
Roll a new friend each week through a gacha system — from lizards to baby dragons, each with its own evolved form and personality. A dex screen tracks every species you meet, with rarity rings that light up once completed.
Reacts to real time and weather
Tamamon responds to the actual time of day and weather outside. When it rains or night falls, your pet heads home to rest. The habitat shifts with the seasons, and your friend's mood changes right along with it.
Your work stays completely private
Tamamon has no servers, no accounts, and no tracking of its own. It reads only your Claude usage numbers — never your code or conversations — and nothing about your work ever leaves your Mac.
What stands out
A desktop pet that reads your Claude usage, not your code — and keeps everything local on your Mac.
This privacy-first approach is rare among developer tools. Tamamon doesn't just promise privacy; it's built without any infrastructure to collect data. It reads only your live session and weekly Claude usage numbers straight from your Claude Code login, with no key or setup required. The result is a companion that grows with your actual work without ever seeing what you're building.
Worth checking out if…
You spend long hours in Claude Code and want a subtle, non-intrusive companion that rewards your consistency. Tamamon fits best for macOS 15+ users on Apple Silicon who value privacy, enjoy collecting virtual creatures, and want a desktop pet that reacts to real-world weather and time without ever uploading a single byte of your work.
