A desktop pet for your Mac that reacts to everything you do

Capybara Pet is a small pixel-art capybara that sits above your windows on macOS. He watches your cursor, taps a tiny keyboard while you type, and keeps you company through long working days.

What a Mac desktop pet should be

Most desktop pets are novelties: they wander around, get in the way and eat memory. Capybara Pet is built the other way round. He lives in a corner of your screen, clicks pass straight through him, and he only reacts to things you actually do, such as moving the mouse, typing, scrolling, dragging him, or leaving your desk.

Made for macOS

  • Native Apple Silicon and Intel builds. Download the .dmg that matches your Mac (Apple menu, About This Mac, then look for "Chip").
  • Lives in your menu bar. There is no Dock icon. Settings, the Pomodoro timer and Peek mode are all in the menu bar icon.
  • Works across Spaces and full-screen apps, so he is there when you switch desktops.
  • Peek mode (Cmd + Alt + P) tucks him below the screen edge while you present or watch a video.
  • Private by design. macOS asks for Accessibility permission so he can notice that a key was pressed. He never reads which key, and nothing is recorded or sent anywhere.

What he does

He follows your cursor with his eye and turns to face it. Type, and a little two-button keyboard slides out and his paws tap along. Type fast and he overheats. Drag him and he stretches like mochi; shake him and he gets dizzy. Stroke his head with the cursor and he purrs. Leave the Mac alone for a minute and he gets drowsy, yawns, then falls asleep.

Useful as well as cute

Capybara Pet can remind you to stretch and drink water, run a Pomodoro focus timer next to him, show a pinned note, and call you by name. If you use an AI coding tool such as Claude Code, he can tell you when it has finished, see Claude Code notifications.

First launch on a Mac

  1. Open the .dmg and drag Capybara Pet into Applications.
  2. The app is not yet notarized by Apple, so open System Settings, Privacy & Security, and click Open Anyway once.
  3. Switch Capybara Pet on under Accessibility so he sees your typing. He picks it up within seconds.
  4. Paste your activation code when asked.

Frequently asked questions

Does it work on Apple Silicon (M1, M2, M3, M4)?

Yes. There is a native Apple Silicon build and a separate Intel build, both on the download page.

Which macOS versions are supported?

macOS 12 Monterey or later.

Does it slow my Mac down?

No. He is a tiny pixel canvas that redraws a handful of rectangles per frame and sits idle when nothing is happening.

Why does it ask for Accessibility permission?

So it can tell that you are typing or scrolling in other apps. It only learns that a key was pressed, never which key. Without the permission everything else still works.
