Kite3D

Build 3D games in your browser with AI

---

Quickstart

Paste this prompt into your agent:

use npx kite3d and build me an FPS shooting practice game

Or manually install:

npx kite3d init my-game
cd my-game && npm install
npx kite3d dev        # local editor, keeps running while you edit

The first init or dev on a machine registers a kite3d:// link, so the "Open engine" button on kite3d.dev opens the picker of every project on that machine. npx kite3d open does the same from a terminal.

Features

• Agent-native. One prompt builds a game. The CLI teaches the loop and ships its source to grep.
• ECS. Behavior lives in components attached to scene nodes, one script each.
• Text glTF scene. Agents and humans edit the same file. Git diffs it. Saving an unchanged scene writes the same bytes.
• Hot-reloaded components. Save a script, the editor swaps it in place.
• Play in the editor. Play, pause, pick and move objects in the paused world, resume, stop back to the saved scene.
• Local browser editor. Served from your folder. No account.

CLI

Command	Does
kite3d init <dir>	Create a project
kite3d dev	Start the local editor for the project in the current folder
kite3d open	Open the project picker: every project on this machine, running ones marked
kite3d install	Register the kite3d:// link by hand; --remove undoes it
kite3d screenshot	Save a PNG of the editor viewport
kite3d skills	List bundled skills with absolute SKILL.md paths
kite3d publish	Print the bundled publishing procedure path

npx kite3d skills lists skills bundled with the invoked CLI and works outside a project, including from an npx cache or global install. Pass --json for structured output.

Run npx kite3d with no argument for the full list.
