## Why Pion WebRTC?

Pion WebRTC enables you to build WebRTC applications outside the browser with the reliability and performance of Go.

### Pure Go Implementation

<CardGroup cols={3}>
  <Card icon="golang" title="No CGo Required">
    Written entirely in Go with zero C dependencies. Build once, run anywhere.
  </Card>

  <Card icon="microchip" title="Cross-Platform">
    Supports Windows, macOS, Linux, FreeBSD, iOS, Android, and WebAssembly.
  </Card>

  <Card icon="gauge-high" title="Fast Builds">
    Build the entire library in under 1 second. Run full test suite in \~77 seconds.
  </Card>
</CardGroup>

### Standards Compliant

<Note>
  Pion implements the official W3C [webrtc-pc](https://w3c.github.io/webrtc-pc/) and [webrtc-stats](https://www.w3.org/TR/webrtc-stats/) specifications.
</Note>

If you know how to use WebRTC in the browser, you already know how to use Pion WebRTC. The API mirrors the JavaScript WebRTC API for a familiar developer experience.

## Key Features

### PeerConnection API

* **Full WebRTC API** - Complete implementation of PeerConnection, DataChannels, and Media APIs
* **Send/Receive Media** - Audio and video streaming with codec support for Opus, VP8, VP9, H264, AV1
* **Data Channels** - Ordered/unordered, reliable/unreliable messaging
* **Renegotiation** - Dynamic track and data channel management
* **Plan-B & Unified Plan** - Support for both SDP semantics
* **SettingEngine** - Pion-specific extensions for advanced control

### Connectivity

<Steps>
  <Step title="Full ICE Agent">
    Complete Interactive Connectivity Establishment with ICE restart and Trickle ICE support
  </Step>

  <Step title="STUN/TURN Support">
    Built-in STUN support and TURN support via UDP, TCP, DTLS, and TLS
  </Step>

  <Step title="mDNS Candidates">
    Local network discovery without STUN servers
  </Step>
</Steps>

### Media Capabilities

```go theme={null}
// Direct RTP/RTCP access for custom processing
track, err := webrtc.NewTrackLocalStaticRTP(
    webrtc.RTPCodecCapability{MimeType: webrtc.MimeTypeVP8},
    "video",
    "pion",
)
```

* **Codec Support** - Opus, PCM, H264, VP8, VP9, AV1 packetizers
* **Container Formats** - IVF, Ogg, H264, and Matroska readers/writers
* **Advanced Features** - Simulcast, SVC, NACK, Sender/Receiver Reports, TWCC
* **Easy Integration** - Works with x264, libvpx, GStreamer, and FFmpeg

### Security

<Warning>
  All connections are encrypted by default using industry-standard protocols.
</Warning>

* **DTLS v1.2** - TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_GCM\_SHA256 and TLS\_ECDHE\_ECDSA\_WITH\_AES\_256\_CBC\_SHA
* **SRTP** - SRTP\_AEAD\_AES\_256\_GCM and SRTP\_AES128\_CM\_HMAC\_SHA1\_80
* **Hardware Acceleration** - Available for GCM cipher suites

## Design Principles

### Portable

Written in pure Go with no C dependencies. If Go runs on your platform, Pion WebRTC will too. Cross-compile with a single `go build` command.

### Flexible

Pion leaves decisions to you. Choose your own logging library, media sources, and signaling mechanism. We provide the transport layer, you provide everything else.

### Simple API

The API mirrors the browser WebRTC API. Your WebRTC knowledge transfers directly from browser to server.

### Bring Your Own Media

Pion doesn't make assumptions about your media sources. Use FFmpeg, GStreamer, camera devices, files, or anything else. Pion handles the transport.

### Safe & Tested

Built with Go's safety guarantees and concurrency primitives. Every commit is tested, and the codebase maintains high test coverage.

### Readable

Code references RFCs with links to specifications. Learn WebRTC internals while using the library.

## Use Cases

<Tip>
  Pion WebRTC powers real-world applications across industries:
</Tip>

* **Video Conferencing** - Build scalable conferencing platforms with server-side processing
* **IoT & Robotics** - Stream camera feeds from embedded devices directly to browsers
* **Broadcasting** - Send video files to multiple browsers with perfect synchronization
* **Secure Communications** - Create peer-to-peer encrypted data channels between servers
* **Recording & Processing** - Capture and process audio/video streams server-side
* **Remote Control** - Control robots and stream telemetry in real-time
