Powering the Internet of Life

Build reality. Together.

Describe a 3D app to your coding agent. Share one link. Everyone joins from the web, desktop or phone.

The Internet of Life is TMRW's name for an internet you step into: shared spaces where people meet and work together as naturally as in real life. RealityOS is the engine it runs on.

Under the hood

A WebGPU engineA WebGPU engine: real-time 3D in any modern browser, with a Rust core

One TypeScript SDKOne TypeScript SDK: familiar if you know three.js

Multiplayer built inMultiplayer built in: everyone in a scene sees the same thing, live

Vision on the deviceVision on the device: people from their camera put into the scene, plus tracking and clean speech

The platform

Everything a 3D app needs, from one place

Engine

A Rust core that renders with WebGPU, with multiplayer sync and on-device vision built in.WebGPU rendering, sync and on-device vision.

SDK

One TypeScript SDK for apps, tools and AI agents, in the idioms three.js developers know.One TypeScript SDK for people and agents.

Multiplayer

Shared scenes that stay in sync for everyone in them, people and AI agents alike.Shared scenes, in sync for everyone.

Built for agents

Write it in TypeScript, or let your agent write a scene file.

Every RealityOS scene can be written as TypeScript or as a typed scene file. Both drive the same engine, so a developer and an AI agent can work on the same app.Code or a scene file: both drive the same engine.

Scene filesA whole scene as versioned JSON with typed components, easy for an agent to write and check.Scene files. Typed JSON an agent can write.
Familiar codeScenes, meshes, lights and cameras, named the way three.js developers expect.Familiar code. three.js idioms.
One engine underneathWhat an agent writes renders exactly like what a developer writes.One engine. Same result either way.
