What it is

VibeSail is a three.js sailing game that runs in the browser with no download. Its developer says it has grown to more than 200,000 lines of code and 1,000 commits over 20 months, and that an AI data broker offered to buy its source code and git history to train frontier models.

How it was built with AI

Asked how he built the game, developer Nicola Manzini replied: 'I used all the main ai agents. Cursor, codex, Claude, antigravity, conductor ... I just talk to it. I am a programmer btw.' He added that he now mostly uses Cursor.
