Frequently Asked Questions
It’s a free-to-play, multiplayer flight simulator you can play in your browser at fly.pieter.com. Created by Pieter Levels in February 2025, it’s a simple 3D game where you fly planes, dogfight with others, and explore a basic world with cliffs, a runway, and later Mars. It’s unpolished but gained fame for being built in just three hours using AI tools.
Pieter Levels, an indie developer with no prior game dev experience, used AI tools like Cursor (an AI code editor) and xAI’s Grok to build it. He gave the AI prompts like “make a 3D flying game in the browser,” and within three hours, he had a working prototype in vanilla HTML and JavaScript. The speed and AI angle are why it went viral.
Go to fly.pieter.com, press any key to start, and you’re flying a plane. Use your mouse or keyboard to steer (it’s basic—left/right, up/down). You can dogfight other players in real-time thanks to its multiplayer setup with PeerJS and WebSockets. There’s no deep tutorial; it’s meant to be intuitive and messy.
It’s free, but Levels added a $29.99 microtransaction for an F-16 plane after it blew up. It’s cosmetic, not pay-to-win, though some X users griped about it, calling it a cash grab on a “bare-bones” game.
