MACOS DESKTOP PET

A tiny friend that grows as you code

Work in Claude Code and your egg hatches, grows, and evolves. Tamamon is a little pixel creature that wanders quietly across your desktop.

Download for macOS macOS 12+ · Apple Silicon

Reads only your local Claude activity. Nothing ever leaves your Mac.

HOW IT WORKS

Three steps to your first friend

No dashboards, no chores. Install it once and just keep coding.

1

Install & run

Tamamon settles in along the bottom of your screen, resting above your other windows.

2

Code with Claude

Your Claude Code activity quietly feeds the egg — no account, API key, or setup needed.

3

Watch it grow

It hatches, grows through stages, and evolves. Feed and play to keep it happy.

GROWTH

From egg to evolution, together

Every bit of Claude Code usage nudges your friend forward — one stage at a time, never backward.

  1. Egg stage Egg
  2. Baby stage Baby
  3. Adult stage Adult
  4. Evolved stage Evolved

FEATURES

Small, but truly alive

A desktop pet that reacts, remembers, and grows — without getting in your way.

Grows with you

Your coding activity hatches the egg and levels it up. Neglect it and it sulks; care for it and it beams.

20 to collect

Roll a new friend each week — from lizards to baby dragons, each with its own evolved form and quirks.

Weather & time

It reacts to the real time and weather. Rain sends it home; nightfall brings sleepy stars.

Feed, play, decorate

Feed snacks, play with balls and bubbles, and decorate its nest. A cozy home keeps it calm.

Always on top

It strolls above your other windows, quietly living along the bottom of your workspace.

Local only

Usage is read on your Mac alone. No servers, no accounts, no tracking — ever.

LIVING WORLD

Seasons and days pass with you

PRIVACY

Quietly, on your Mac

Tamamon is a companion, not a data collector. Here's exactly what it does.

Nothing leaves your Mac

It reads only local Claude Code activity to grow. No uploads, no account, no tracking.

Featherlight

A small overlay along the bottom of your screen. It never blocks your work or steals focus.

Requirements

macOS 12+ on Apple Silicon. Signed & notarized for a safe, one-click install.

FAQ

Good to know

Is it free?

Yes, completely free. If you'd like, you can tip on Ko-fi to buy Tamamon a snack — but you never have to.

What does it read?

Only your local Claude Code activity, on your Mac. It never sends anything to a server.

Do I need to connect an account?

No. Tamamon just watches local usage to grow — no login and no API key required.

What happens if I don't code for a while?

Your friend gets hungry and sulks, but it won't vanish. Feed it and it bounces right back.

Which Macs are supported?

macOS 12 (Monterey) or later, on Apple Silicon.
