What is iR Engine?

iR Engine is a free and open-source mixed reality engine for Web AR, VR, and XR apps. It is an ideal solution for creating web-based apps that can run anywhere.

Supported platforms

Linux, Windows, and macOS

Requirements

Linux (many of us develop on Ubuntu), Mac OS X, or Windows (we recommend WSL2)
Node.js v18 or later (we recommend installing via nvm or asdf.)
C++ (for node-gyp), Python >=3.6 + PIP, make and other build tools, for compiling Mediasoup. Although most of iR Engine is written in TypeScript, it uses a Mediasoup engine for WebRTC conferencing. See the Mediasoup install instructions for more details.
Docker. (Although Docker is technically optional, running iR Engine requires starting up half a dozen different services, and using Docker Compose will make your life dramatically easier.)
MariaDB and Redis. (If you're using Docker, containers for MariaDB and Redis will automatically be started up.)
