About:
Wslay is a lightweight C library designed for WebSocket protocol handling, focusing on the framing layer without external dependencies. It provides an event-driven API that simplifies building both WebSocket servers and clients by managing message parsing and data transmission efficiently. Its main value proposition is enabling high-performance, low-overhead WebSocket implementations in C applications.
Key Features:
  • Event-driven API for non-blocking I/O
  • Minimal dependencies (only zlib and OpenSSL for TLS)
  • Supports both client and server roles
  • RFC 6455 compliant
Use Cases:
  • Implementing real-time features in C-based web servers
  • Building custom WebSocket clients for embedded systems
  • Adding WebSocket support to existing network applications
Alternatives:
  • libwebsockets – More feature-rich but larger and more complex
  • WebSocket++ – C++ library with Boost dependency, higher abstraction
