## What it is
AR.js is a lightweight JavaScript library for augmented reality on the web, supporting image tracking, marker tracking, and location-based AR. It integrates with A-Frame and Three.js and runs directly in the browser without any app installation.

## Use cases
- add marker-based augmented reality to a website
- build a web AR experience with image tracking
- create location-based AR content in the browser
- overlay 3D models on camera feed without installing an app
- build AR with A-Frame or Three.js
- show geolocated AR points of interest on mobile browser

## When to choose
- you want lightweight, marker-based or location-based AR in the browser
- you are already using A-Frame or Three.js
- you need a no-install web AR solution with MIT license

## When to avoid
- you need advanced multi-image or face tracking - consider MindAR instead
- you need native mobile AR performance like ARKit/ARCore
- you need SLAM-based world tracking
