A pure Go implementation of the WebRTC API for building real-time communication applications.
Pion WebRTC is a pure Go implementation of the WebRTC API that enables developers to build real-time communication applications for audio, video, and data transfer. It solves the problem of establishing peer-to-peer connections in Go applications without relying on browser-based WebRTC or external C dependencies, making it suitable for server-side and embedded use cases.
Go developers building real-time communication systems, such as video conferencing apps, IoT device streaming, server-to-server data transfer, or embedded media applications.
Developers choose Pion WebRTC for its pure Go implementation, which ensures portability across many platforms (including WebAssembly), ease of deployment, and no external C dependencies. It provides a fully-featured, standards-compliant WebRTC stack with advanced media handling and strong security.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
No Cgo dependencies enable easy cross-compilation for a wide range of platforms including Windows, macOS, Linux, iOS, Android, and WebAssembly, simplifying deployment and avoiding external library issues.
Implements full WebRTC PeerConnection API with data channels, audio/video transmission, and session renegotiation, adhering to webrtc-pc and webrtc-stats standards for interoperability.
Supports simulcast, SVC, NACK, congestion control, and bandwidth estimation, with provided examples like simulcast and bandwidth estimation from disk, enhancing real-time performance.
Allows easy integration with x264, libvpx, GStreamer, and ffmpeg for media processing, and offers direct RTP/RTCP access for custom implementations.
Major version upgrades like v4.0.0 introduce breaking changes, requiring careful migration and explicit version specification in imports, which can disrupt ongoing projects.
Requires deep understanding of WebRTC protocols such as ICE, SCTP, and DTLS; the project recommends external resources like 'WebRTC for the Curious' for effective debugging and usage.
For features like getUserMedia, Cgo is required, and media handling often needs integration with external libraries, adding complexity compared to all-in-one solutions.
