Dev builds a browser-based 3D world with Hyperfy, vibe-coding a realistic pool table in 15 minutes
remorej · reddit · 2026-10-22
Inspired by the Bobiverse novels, a developer built a personal 3D virtual world with Hyperfy, an open-source engine that runs entirely in the browser (JavaScript, React, Three.js), self-hosted like any website. His fork features a detailed night sky and just integrated a billiards engine for a realistic pool table — 15 minutes of Codex 6.1 Medium usage. Everything is generated by ChatGPT/Codex via a '3D prompt box' that exports a zip of models merged back into the world. Independent worlds connect via portals, like hyperlinks between homepage and homeworld.
