Vibe coded by Geo

Multiplayer Minecraft Made With AI

An AI Minecraft clone: a persistent multiplayer voxel world you play in the browser. The entire codebase was generated by ChatGPT Codex 5.3. It took many days of human testing and fixing, but no code was written by a human.

What Is This?

Vibe Craft is an experimental, server-authoritative AI Minecraft clone (Minecraft-style voxel sandbox). Your browser is the client. The server generates, simulates, and stores the world so it persists between sessions.

If you searched for "AI Minecraft clone" or "Minecraft made with AI", this is the idea pushed into something you can actually join: chunks stream in, you can mine and place blocks, craft, fight mobs, and explore together.

How The “AI-Made” Part Works

This project was produced entirely by ChatGPT Codex 5.3 through an iterative loop: prompt, run, test, report bugs, and regenerate improvements. Humans directed the work and did extensive testing, but did not manually write code.

The result is a purely AI-generated multiplayer Minecraft clone with real constraints: performance budgets, chunk streaming, persistence, and keeping clients in sync.

What You Can Do In-Game

  • Explore an infinite chunked world with biomes, rivers, caves, and mountains.
  • Mine and place blocks, pick up dropped items, and manage your hotbar + inventory.
  • Craft, use a furnace, open chests, and survive with health + damage.
  • Meet animals and hostiles (night spawns), with multiplayer-synced entities.
  • Use commands like /spawn, /give, /time, /home.

Tech Notes (For The Curious)

  • Rendering: Three.js + WebGL with texture packs, fog, sky cycle, and chunk instancing.
  • Server: Node.js + WebSockets for chat, player state, chunk streaming, and persistence.
  • World: Chunked terrain generation with biomes, fluids, light sources, and edits saved to disk.
  • Map: Server-driven surface sampling rendered as a flat top-down map at /map.

FAQ

Is this official Minecraft?

No. This is a fan-made experiment and is not affiliated with Mojang or Microsoft.

Is there really zero human-written code?

The code was generated by ChatGPT Codex 5.3. Humans directed the work and did many days of testing and fixing via feedback, but did not manually write code.
