Free-to-play multiplayer flight simulator in your browser where you dogfight with other players online.

One guy. Three hours. A flight simulator, built inside a browser. Pieter Levels prompted Cursor and Grok to build from scratch, vibe coded almost entirely live on X. 17 days later: $87K a month. 320,000 people dogfighting strangers online. Elon Musk tweeting about it. The money came from ad slots on the terrain, zeppelins, billboards, about $5K a pop, sold straight from his own account. No team. No pitch deck. Just a guy shipping alone with tools most of us already pay for. This is what solo looks like now. #buildinpublic

Bid to own this web page in real-time competition with other companies.

Nice one 😄 Just launched a small experiment tonight: Instead of another crowded leaderboard, one company gets the entire homepage until someone pays more and takes it. Current takeover is still very low, so if anyone wants to try it early, now is probably the best time 📷👀
