websocat
A command-line tool for interacting with WebSockets, offering netcat/curl/socat-like functionality with advanced proxying and bridging capabilities.
What is websocat?
Websocat is a command-line client and server for WebSockets that functions like netcat, curl, or socat for ws:// and wss:// protocols. It allows developers to interact with WebSocket endpoints directly from the terminal, enabling tasks such as connecting to echo servers, serving WebSocket connections, and proxying between WebSockets and other network protocols like TCP.
Developers, DevOps engineers, and system administrators who need to test, debug, or integrate WebSocket-based services in scripts, automation, or network troubleshooting scenarios.
Websocat stands out by offering advanced socat-like functionality—such as protocol bridging, message transformation, and external program execution—within a single, cross-platform tool, making it more powerful than basic WebSocket CLI utilities.
