WebSocket++ is a header only C++ library that implements RFC6455 The WebSocket Protocol. It allows integrating WebSocket client and server functionality into C++ programs. It uses interchangeable network transport modules including one based on raw char buffers, one based on C++ iostreams, and one based on Asio (either via Boost or standalone). End users can write additional transport policies to support other networking or event libraries as needed.

Major Features

• Full support for RFC6455
• Partial support for Hixie 76 / Hybi 00, 07-17 draft specs (server only)
• Message/event based interface
• Supports secure WebSockets (TLS), IPv6, and explicit proxies.
• Flexible dependency management (C++11 Standard Library or Boost)
• Interchangeable network transport modules (raw, iostream, Asio, or custom)
• Portable/cross platform (Posix/Windows, 32/64bit, Intel/ARM/PPC)
• Thread-safe
