FuFu Siamese desktop pet
FuFu stays quiet while you focus, then waves when it is time for a reminder.

Meet FuFu

A little desktop companion

Drag the cat wherever you like, resize it, and let it quietly sit beside your work.

Small reactions that feel alive

Clicks, drags, reminders, and automatic actions can trigger reviewing, jumping, waiting, and running animations.

Rest and water reminders

Customize rest intervals, water intervals, bubble duration, and lower-distraction behavior.

Supports PetDex pets

SlackerBuddy is not limited to the default FuFu pet. It supports PetDex pet packages, so you can pick a desktop pet you like, download it, place it in your local pet folder, and switch to it from SlackerBuddy settings.

Open PetDex to choose a pet
  1. Go to PetDex, choose a pet you like, and click download pet.
  2. Put the downloaded pet folder into ~/.codex/pets. Each pet usually includes pet.json and a spritesheet image.
  3. Open SlackerBuddy from the menu bar, go to settings, and choose your new PetDex pet from the Pet option.
  4. If settings is already open, reopen it or switch the pet picker once so SlackerBuddy refreshes the available pets.
