A command-line client for WebSockets that provides netcat/curl-style access to ws:// endpoints, letting users connect to and serve WebSockets, pipe a program’s stdin/stdout to a socket, proxy TCP to WebSocket traffic, and broadcast between clients. Intended for backend developers testing WebSocket APIs and engineers scripting real-time integrations; it is open-source and maintained on GitHub.
