## What it is
A JavaScript library that layers a WebRTC datachannel-based peer-to-peer network on top of hls.js, letting viewers share HLS video segments with each other for live and VOD streams. It acts as a P2P overlay CDN that reduces bandwidth costs and falls back seamlessly to normal server delivery when WebRTC is unavailable.

## Use cases
- reduce video streaming CDN bandwidth costs with p2p
- scale live streaming to large audiences without a bigger CDN
- add peer-to-peer HLS streaming to an hls.js player
- integrate p2p video delivery with video.js or JWPlayer
- offload video traffic from origin server during viewership spikes
- deliver VOD streams via webrtc data channels

## When to choose
- You already use hls.js or a popular HTML5 player and want P2P offload with minimal code changes
- You have audiences large enough that many peers are online simultaneously
- You want a hybrid setup that keeps your existing CDN, DRM, and encoding pipeline intact

## When to avoid
- You need iOS Safari support in this engine (MediaSource unsupported there; use the ServiceWorker variant instead)
- You need fully self-hosted delivery - the tracker/signaling and dashboard are a paid hosted service
- Your audience is small or geographically sparse, so few peers can connect
- You require a permissive license - the repo has no license file
