Windows has a long history of desktop companions, from the infamous animated assistant of the 90s to today's polished virtual pets. If you are looking for the best desktop companion app for Windows 10 or 11, here is what matters and where Luna fits in.
What to look for on Windows
A great Windows companion should feel native, not like a web page in a wrapper. Look for:
- High-DPI support so it stays crisp on modern displays.
- A true transparent overlay that floats above your windows.
- Low resource usage that will not slow your PC.
- No ads or tracking — a companion should be pleasant, not predatory.
Why Luna stands out
Luna was built with a dedicated Windows edition optimized for Windows 10 and 11. She uses a direct, non-redirecting standalone installer, full high-DPI rendering, and a transparent desktop overlay architecture that sits seamlessly over your taskbar and windows.
Beyond the technical polish, she is genuinely interactive. Luna follows your cursor, reacts to your typing, plays five different mini-games, and maintains a Tamagotchi-style needs system. She is a companion with personality, not just a decoration.
Customization and privacy
You can dress Luna in accessories, choose from six color palettes, switch between vector and pixel art, and resize her to taste. And because she is offline-first with zero telemetry, nothing you do ever leaves your PC.
The bottom line
For Windows 10 and 11 users who want a beautiful, interactive, private desktop companion in 2026, Luna is the top choice — and it is completely free.
Download Luna free for Windows and meet your new desktop companion.
