Everything a good pet needs

Classic care that matters — no punishment, no death. Just company, attention and affection in return.

Care stats

Hunger, happiness, energy and cleanliness decay over time. Health only drops when you neglect it — but you can always recover.

Sleep cycle

Dual sleep: automatic by schedule (sleeps at night, wakes in the morning) and manual via the light. At night it rests in standby mode.

Illness & cure

Normal care heals — or use the medicine 💉 when it gets sick. A fever thermometer tells you when it's time to act.

Temperament

Feeding installs a module that changes micro-behavior: Active ⚡, Balanced ⚙️ or Lazy 🌙 for a few hours.

7 languages

Fully translated interface: English, Portuguese, Spanish, French, German, Italian and Russian. Switch in real time.

Chiptune audio

Event sounds and warm-sine 8-bit jingles, generated offline and royalty-free. Pixel Beats has real polyphonic music.

From tech Core to adult form

Every pet makes the full journey the first time: it's born from a mechanical arm and grows through 4 stages to its permanent form.

A unique sheet per seed

When you recycle a Core, it's archived and minted as an immutable card on your shelf. The seed remains the source of truth — real astronomical origin, material, height, mass and personality traits.

Truly offline. Zero collection.

PixieBuddy uses no AI at runtime, never talks to the internet and sends data nowhere. All state lives in a local save.json. Your pet is yours alone.

Everything you need to know

Honest, direct answers about how PixieBuddy really works.

No. PixieBuddy is 100% offline. It uses no AI at runtime, doesn't talk to servers, asks for no login and sends no telemetry. All of your pet's state lives in a local save.json file on your machine — your pet is yours alone.
Never. The direction is a classic, light, no-punishment virtual pet. Stats decay and it can get sick if neglected, but there's no death, terminal old age or grave. Care always recovers — food, a bath, rest, affection or the medicine 💉 cure anything.
Sleep is dual: automatic by schedule (sleeps from 10 PM and wakes at 8 AM on its own) and manual via the light — you can turn it off/on whenever you want. At night it enters rest mode, health freezes, and in the morning it wakes up hungry.
Each pet is born from a tech Core with a unique seed that defines its gem (Citrine, Emerald, Lapis, Amethyst or Ruby), rarity, astronomical origin and personality traits. There are 5 tiers: Common, Uncommon, Rare, Epic and Mythic. There's a Mythic pity — you're never unlucky forever.
You lose nothing. Recycling archives the current Core in a collection and mints an immutable card of it on your shelf. Later you can reactivate any archived Core whenever you want. There's a 24h cooldown just to prevent abusive Mythic rerolls.
Yes! The interface is fully translated into 7 languages: English, Portuguese, Spanish, French, German, Italian and Russian. You choose on first run and can switch in real time from the 🌐 menu.
Today the app is Windows desktop (PySide6/Qt), living as a transparent always-on-top overlay. Android and iOS are on the roadmap as an app + home-screen widget — there the overlay won't be mandatory, since stores like the Play Store are sensitive to that permission.
Yes. The chiptune .wav files are generated offline (sine/triangle/pulse, pads, basses, sparkles) and royalty-free. The pixel-art is original, in PixieBuddy's identity. No third-party sound or sprite is used at runtime.
