About fly.pieter.com

A browser-based MMO flight simulator: open the page and you are flying, with other players in the same sky and nothing to download. You can pick a free Cessna, a free "Cyberpink" jet or an F-16 sold in-game, and startups can buy ad placements inside the world. Pieter Levels, an indie founder with no previous game-development experience, built the first version in a few hours in February 2025 (reports range from 30 minutes to about three hours) and kept extending it in public. The game's own page credits "@levelsio + Cursor + ThreeJS" and calls it "100% made with AI". It became one of the best-known examples of a vibe-coded game, and its creator's public revenue claims were widely reported.

Development approach

Prompt-driven solo development in Cursor, with Three.js for 3D rendering. Features were added after launch in response to players, in public on X. Some secondary articles also name xAI's Grok; no statement from the developer confirming that was found, so it is not recorded.
