A free-to-play browser MMO flight simulator you open in a tab — no download, no long update queue. Pieter built it as his first vibe-coded game after getting tired of Microsoft Flight Simulator’s load times. The game went massively viral on X; he later documented the saga reaching $1M ARR in 17 days.

Build story Shipped live on X starting 22 Feb 2025. He prompted Cursor (with Claude) to make a 3D browser flying game — first game he’d ever made — and had a playable sim in about three hours. Later iterations added multiplayer and other features while building in public.
