This project enables developers to build XR experiences using the same code that runs on the web. Exokit engine is written on top of Node and emulates a web browser, providing native hooks for WebGL, WebXR, WebAudio, and other APIs used in immersive experiences.

Exokit targets the following platforms:

• Desktop VR (Steam compatible)
• Magic Leap
• Mobile AR (ARKit / ARCore) *
• Mobile VR (Daydream / Gear VR) *
• Standalone VR (Oculus Quest/Go) *

* not supported yet

Since Exokit supports anything that runs on the web, it powers experiences built with:

• Three.js
• Unity
• Pixi.js
• Babylon.js
• A-Frame
• Custom WebGL frameworks
• WebAssembly, TypeScript, and any language that transpiles to JavaScript

• The future is immersive. The web is the best application platform. Javascript is the best ecosystem.
• Content should be hardware agnostic. Tomorrow will have different hardware. VR and AR should be compatible.
• It's not possible to do both 2D and 3D well. We don't do 2D. We can use an external 2D browser.
• Use your favorite game engine. Exokit is not a game engine.
• Legacy browser design choices don't make sense in XR.
• Exokit empowers and connect apps, even (especially) if they aren't designed to cooperate.
• Apps should run in "reality tabs", layers of reality that blend together.

Exokit is a Javascript Node.js module.

C++ bindings hook into WebGL, WebXR, Magic Leap, Leap Motion, and various other device APIs.

const {window} = require('exokit')() to get an immersive browser in another project.

Exokit runs on Windows, macOS, Linux (x64), Linux (ARM64), and Magic Leap (ARM64).

• You want your WebGL/WebXR to run fast.
• You want the hot new web APIs.
• You want to add your own integrations -- including native -- into a browser environment.
• You want a lightweight browser as a hackable node module.
• You want to combine the web with a 3D engine like Unity.

• You're looking for a "web browser".
• You don't care about 3D or mixed reality.
• You're looking for strict and/or legacy standards support.

Uses ndb.

npm run debug

Then in the console, input:

let window = await require('./src/').load(yourUrl);

Now you have a handle on the window object as you test your application, and you can set debugger breakpoints, inspect memory, profile CPU, etc.
