GOKIs

A macOS desktop critter simulator with two display styles, a menu bar control, and a research-grounded escape behavior.

GOKIs is a small macOS app that drops critters onto your desktop. They scurry away from your cursor, hide behind windows along the edges of the screen, and quietly liven up your workspace without ever taking focus or interrupting your work.

How GOKIs works

  • The app lives in the menu bar (no Dock icon, no main window).
  • A full-screen transparent overlay sits below every normal window, so critters appear behind the apps you are using.
  • Mouse events pass straight through the overlay. Other apps stay fully clickable.
  • The simulation runs on a Metal compute shader, so even thousands of critters stay smooth on Apple Silicon.

Two display styles

GOKIs ships with two interchangeable looks:

  • Keseran Pasaran — a fluffy, friendly mascot. The default display style and the one we show to first-time users.
  • GOKI — a realistic cockroach. Available, but only if you explicitly opt in. The first launch asks “Do you know GOKI?” and the cockroach is shown only when you choose to see it.

You can switch styles any time from the menu bar, though the change requires a restart to take effect.

System requirements

  • macOS 15.0 (Sequoia) or later
  • Apple Silicon (M1, M2, M3, or M4)
