About:
Websocat is a command-line utility for interacting with WebSocket servers and clients. It functions like 'netcat' or 'curl' for the WebSocket protocol, enabling bidirectional communication for testing, debugging, and automation. Its primary value is providing a simple, scriptable interface to work with real-time web protocols directly from the terminal.

Key Features:

Acts as both a WebSocket client and server
Supports SSL/TLS for secure connections (wss://)
Can pipe data between WebSockets and standard input/output
Handles both text and binary WebSocket frames
Includes features for connection tunneling and protocol mocking

Use Cases:

Testing and debugging WebSocket APIs and services
Automating real-time data streams in shell scripts
Creating ad-hoc bridges between WebSocket and other network protocols

Alternatives:

wscat – Node.js-based alternative; simpler but less feature-rich than websocat
curl – General-purpose tool with added WebSocket support in recent versions; less specialized for complex WebSocket interactions
