websocat is a command-line tool for WebSockets, acting like netcat, curl, and socat for ws:// and wss:// connections. It supports both connecting to and serving WebSocket endpoints, with advanced features like proxying between TCP and WebSocket, broadcasting, auto-reconnect, and UNIX socket integration.
Use cases
- test a websocket server from the command line
- run a websocket echo server for debugging
- bridge a TCP connection over a websocket
- pipe stdin/stdout of a program to a websocket
- broadcast websocket messages between multiple clients
- debug browser devtools protocol over websocket
- connect to a websocket through a SOCKS5 proxy
When to choose
- you need a quick netcat-style tool for testing or scripting WebSocket connections
- you want to proxy or bridge TCP and WebSocket traffic from the shell
- you need a lightweight WebSocket server or client without writing code
- you want cross-platform prebuilt binaries for Linux, Windows, and macOS
When to avoid
- you need a WebSocket library to embed in an application rather than a CLI tool
- you need a GUI WebSocket client with saved request collections
- you need production-grade WebSocket load testing or monitoring at scale
