Desktop Terrarium is a native macOS companion that turns real coding activity into a living, animated garden. It automatically detects work in Xcode, Cursor, Codex, Claude and other IDEs—no timers or manual project setup. Project and year progress remain visible in a slim desktop bar, while each focused session grows a richer terrarium. Built with GPT‑6 Astra as an ambitious design and engineering collaborator. One-time $19 license.
