Living Troupe
Every flea has a little personality, a current mood, and a sense of what just happened on stage. The troupe keeps feeling alive even when FleaWinder is quietly idling.
FleaWinder™
An ambient circus where every flea is an autonomous agent
Every flea decides its own actions, builds its own memories, and — on iPhone and Mac with Apple Intelligence — speaks in its own voice via the on-device LLM. The whole troupe runs quietly in the background on your desktop, phone, TV, and watch, powered by your typing and clicks. Free, private, no servers.
Free for Windows, macOS, iOS, Apple TV & Apple WatchThe optional paid license removes the reminder popup and supports an independent creator.
v1.9 — simpler pricing. Free now includes every feature except seasonal packs and the share-card watermark. Supporter ($5 one-time) unlocks both. Patron ($49 one-time) names a flea after you. Existing buyers — your old purchase still counts; you’re mapped to Supporter automatically.
What changed →What Makes v3.0 Different
FleaWinder is an ambient circus where every performer has a tiny point of view.
Private Character Dialogue
Supported Apple devices can make each flea's short replies feel more in-character while keeping private moments on the device. Other surfaces use the same character direction with lightweight local lines.
Tiny Memories
Fleas remember recent moments, favorite wins, and recurring little myths. Tap any performer to see the inner-life view that makes those story beats readable.
Cross-Platform Parity
The same agent core runs on iOS, iPadOS, macOS, tvOS, watchOS, visionOS, Windows, and Linux. No 'lite' platforms — Apple TV ambient mode is a first-class showcase.
Eight Live Acts — Plus Your Own
Tightrope Walker
A daring flea wobbles across the high wire, jolted by every keystroke.
Trapeze Artist
Pendulum physics power death-defying leaps between swinging bars.
Cannon Show
Every mouse click loads and fires the cannon. BANG!
Strongflea
Each keystroke pumps the barbell higher. How high can you go?
Unicycle Rider
Speed and lean respond to your mouse energy in real time.
Juggling Flea
Three balls arc through the air in a mesmerizing cascade powered by your activity.
Fire Breather
A stream of flame erupts with every click—the more energy, the longer the blast.
Motorcycle Jumper
Bugg revs toward tiny ramps, clearing wild gaps and landing in sparks as your energy climbs.
Become a Supporter
v1.9 simplified pricing: every act, every theme, AR, iCloud sync — all free. Supporter ($5) unlocks the seasonal-pack rotator, removes the share-card watermark, removes the desktop reminder popup, and supports the solo developer.
One-time purchase. Not a subscription.
How It Works
Every flea is an autonomous on-device agent. They decide their own actions, build their own memories, and — on iPhone and Mac with Apple Intelligence — speak in their own voice via the local LLM. Your typing and clicking still wind the circus like a music box, but the fleas have minds of their own.
Tap a flea to see their mood, memories, and who they're closest to. Step away and the troupe keeps living — wandering, watching each other rehearse, telling little stories, sometimes refusing your taps when they're not in the mood.
Zero configuration. No accounts. No servers. Every agent decision and every word of dialogue is generated locally on your device. Nothing is ever recorded or transmitted.
A Rich History
Flea circuses have captivated audiences for over 400 years—from 16th-century goldsmiths who harnessed live fleas to demonstrate impossibly tiny metalwork, to Victorian showmen who packed London’s Regent Street with miniature chariot races and cannon shows. FleaWinder™ carries on that tradition, digitally.
