## What it is
mediasoup is a powerful WebRTC SFU (Selective Forwarding Unit) implemented as a Node.js module and Rust crate, with a C++ media worker subprocess handling the media plane. It provides a low-level, signaling-agnostic API for building multi-party video conferencing, broadcasting, and RTP streaming applications.

## Use cases
- build a group video chat application
- create a one-to-many live broadcasting app in real time
- stream RTP audio/video between servers and endpoints
- build a multi-party video conferencing server
- forward WebRTC media with simulcast and SVC support
- integrate WebRTC media handling into a Node.js or Rust backend
- exchange data messages via WebRTC DataChannels or SCTP

## When to choose
- you need a high-performance, scalable SFU for multi-party real-time media
- you want a low-level media library you can integrate into your own application rather than an opinionated standalone server
- you need support for simulcast, SVC, bandwidth estimation, and congestion control
- you want to support both WebRTC and plain RTP input/output
- you prefer handling signaling yourself with full flexibility

## When to avoid
- you want a turnkey video conferencing product with signaling, UI, and rooms included out of the box
- you need media transcoding - mediasoup does not transcode
- you need to interoperate with legacy SIP endpoints without extra work
- you want a simple high-level API rather than a low-level media plane API
- your team cannot handle building the signaling layer and application logic themselves
