libdatachannel is a standalone C++17 library (with C bindings) implementing WebRTC Data Channels, WebRTC Media Transport, and WebSockets with a simplified JavaScript-inspired API. It is lightweight with minimal dependencies, supports multiple TLS and ICE backends, and compiles for POSIX platforms, Windows, and WebAssembly.

Use cases

• add WebRTC data channels to a native C++ application
• establish peer-to-peer connections between native apps and browsers
• stream audio and video using WebRTC media transport in C/C++
• use WebSockets for signaling in a cross-platform app
• compile WebRTC data channel code to WebAssembly for the browser
• avoid building Google's heavyweight libwebrtc reference implementation

When to choose

• you need WebRTC data channels or media transport in C/C++ with a small dependency footprint
• you want browser-compatible peer-to-peer connectivity from native applications
• you need a portable WebRTC library across Linux, macOS, Windows, iOS, and Android
• you prefer a simple JavaScript-like API over Google's reference libwebrtc

When to avoid

• you need the full WebRTC feature set such as advanced codecs or simulcast available only in Google's libwebrtc
• you are building in a language better served by native bindings like Rust or Node.js packages
• you need a managed high-level WebRTC service rather than a low-level library
