## What it is
Babylon.js is an open-source 3D game and rendering engine for the web, written in TypeScript and built on WebGL, WebGPU, and Web Audio. It provides a complete scene graph, PBR rendering, physics, animation, and WebXR support in a friendly JavaScript framework.

## Use cases
- build 3d games that run in the browser
- render interactive 3d scenes with webgl or webgpu
- create webxr and vr experiences
- build product configurators and ecommerce 3d viewers
- visualize digital twins and iot data in 3d
- develop metaverse-style web applications

## When to choose
- you need a full-featured 3d engine with rendering, physics, audio, and xr in one framework
- you want strong typescript support and npm packages with tree shaking
- you need webgpu features like gaussian splatting, frame graphs, and clustered lighting
- you want an active community, playground, and extensive documentation

## When to avoid
- you are building a native mobile or desktop game outside the browser (consider Babylon Native or a native engine instead)
- you only need lightweight 2d graphics or simple DOM animations
- you need a tiny bundle for a simple site - a full 3d engine is heavy

## Facets
- artifact type: framework
- maturity: stable
- function: game-engine, graphics, animation, audio-processing, ui-components
- domain: graphics, web-development, simulation
- platform: browser, cross-platform
- tags: 3d-rendering, webgpu, webgl, webxr, pbr, physics, scene-graph, playground, digital-twin, metaverse, game-development, web-server, typescript, javascript
