WebSocket++ is a header-only C++ library implementing RFC6455 (The WebSocket Protocol) with both client and server functionality. It uses interchangeable transport policies (raw buffers, iostreams, or Asio) and supports TLS, IPv6, proxies, and compression extensions.

Use cases

• add a websocket server to a C++ application
• build realtime web dashboards for existing C++ systems
• implement a websocket client in C++
• decode websocket frames with minimal dependencies
• add secure wss/TLS websocket support to a C++ program

When to choose

• you need websocket client/server in C++ with flexible transport and dependency choices
• you want a header-only, cross-platform, low-overhead websocket implementation
• you need to retrofit realtime web interfaces onto older C++ codebases

When to avoid

• you want a batteries-included, opinionated websocket framework with active rapid development
• you are not working in C++ or need C++20/23 idiomatic APIs
• you need extensive hand-holding documentation or a large community
