## What it is
A JavaScript polyfill implementing the WebVR spec so VR content runs on browsers and devices without native WebVR support. WebVR has been deprecated in favor of WebXR, so this project is preserved for historical interest.

## Use cases
- run WebVR content in browsers without native support
- smooth over inconsistencies between WebVR implementations
- add VR support to mobile web experiences
- test WebVR apps on desktop without a special browser build

## When to choose
- maintaining legacy WebVR content that must run on devices lacking native support
- targeting older mobile browsers with inconsistent WebVR implementations

## When to avoid
- starting new XR projects - use the WebXR Device API instead
- needing modern VR/AR features, performance, or ongoing support

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, middleware
- domain: web-development, graphics, gaming-tools
- platform: browser
- tags: webvr, webxr, polyfill, virtual-reality, deprecated-api, javascript, mobile
