The desktop pet revival is in full swing, and 2026 has more charming options than ever. Whether you want nostalgic pixel art or a modern animated companion, here are the top 5 free desktop pets worth installing this year.
What we looked for
We evaluated each pet on animation quality, interactivity, customization, privacy, and platform support. A great free desktop pet should feel alive, respect your resources, and never bombard you with ads.
1. Luna Desktop Dog
Luna tops our list. She is a fully animated desktop dog with a Tamagotchi-style needs system, five mini-games, two art styles, and six color palettes. She follows your cursor, reacts to your typing, and runs natively on macOS, Windows, and Linux — all with zero telemetry and no cost. For a free app, the polish is unmatched. Download Luna free.
2. Classic pixel critters
Several open-source projects revive the classic on-screen animals of the 90s. They are charming in a retro way but tend to be static, looping the same animation without reacting to your input.
3. Shimeji-style mascots
Shimeji mascots climb around your windows and can be themed with custom sprites. They are fun and highly customizable, though setup can be fiddly and many forks are unmaintained.
4. Minimalist widget pets
Some pets live in your menu bar or system tray as tiny animated icons. They are unobtrusive but offer little genuine interaction.
5. Aquarium and plant companions
Not every desktop companion is an animal. Virtual aquariums and desktop plants provide ambient calm, though they are decorative rather than interactive.
The bottom line
If you want the most complete, interactive, and beautifully animated experience, Luna is the clear pick for 2026 — and she is free on every major platform.
