A macOS desktop pet that grows and evolves as you code with Claude Code.
What it does
Renders an animated desktop pet that hatches and evolves based on local Claude Code terminal usage.
Tracks local token activity and coding sessions to calculate growth stages without cloud connections.
Includes over 50 collectible pixel-art species with distinct evolution paths driven by care quality.
Reacts dynamically to local time and real-time weather, sending pets to rest when night falls or rain starts.
Why it works
Local usage tracking operates completely on-device, satisfying strict privacy requirements for software developers.
Zero-config integration reads local Claude Code session logs automatically without requiring API keys or sign-ups.
Adaptive early growth pacing ensures casual coders see satisfying pet progress alongside heavy power users.
Interactive care mechanics and habitat customization transform routine coding sessions into a rewarding routine.

Overview
Tamamon is a privacy-first macOS desktop pet designed for developers using Claude Code. Floating subtly at the bottom of the screen above active windows, Tamamon reads local Claude Code terminal usage data to hatch, grow, and evolve pixel-art virtual companions. Featuring over 50 collectible Warmthfolk species, real-time weather and day-night reactions, customizable habitat decorations, and an offline architecture, Tamamon offers a charming, distraction-free companion experience without tracking code or sending data off-device.

Founder story
Tamamon was created in 2026 by solo indie developer Jason Jeong. Spending entire days coding inside the Claude Code CLI environment, Jeong wanted a lighthearted desktop companion to reflect his daily engineering output rather than another analytical metric dashboard. He built Tamamon as a privacy-focused macOS app that transforms local terminal activity into a virtual pet ecosystem.
Alternatives
Comparison overview
Tamamon calculates pet growth strictly from local Claude Code CLI terminal activity without reading code lines or requiring API keys, whereas generic virtual pet extensions track browser activity or manual timers.
Tamamon operates completely offline on macOS with zero cloud database accounts, unlike multi-device cloud gamification applications.
