## What it is
Ant Media Server is a scalable open-source media server for ultra-low latency live streaming, built around WebRTC (~0.5s latency) with support for SRT, RTMP, RTSP, HLS, LL-HLS, and CMAF. It provides adaptive bitrate, transcoding, recording, REST APIs, and SDKs for web, iOS, Android, Flutter, React Native, and Unity, deployable on-premise or in the cloud.

## Use cases
- run a low-latency live streaming server with sub-second WebRTC latency
- ingest RTMP or SRT streams and deliver HLS/WebRTC to viewers
- build a live shopping, auction, or telehealth video app
- stream IP cameras (RTSP/ONVIF) to browsers with low latency
- transcode live streams to adaptive bitrate ladders
- record live broadcasts and serve on-demand video
- scale live streaming to millions of viewers with clustered origin-edge deployment

## When to choose
- you need sub-second latency interactive streaming (WebRTC) at scale
- you need multi-protocol ingest and delivery (RTMP, SRT, RTSP, HLS, CMAF, WHIP/WHEP) in one server
- you want self-hosted or cloud-deployable streaming with auto-scaling and REST APIs plus mobile/web SDKs

## When to avoid
- you only need simple VOD file hosting or static video delivery via a CDN
- you want a fully free open-source solution with enterprise features like clustering and GPU transcoding (those require a paid license)
- your stack is not Java/Linux-friendly or you need a lightweight embedded media pipeline
