Overview

WebSocket support is available from Bruno 2.13.0.

Bruno now supports WebSocket connections, enabling you to test real-time communication protocols and bidirectional data exchange. This feature allows you to establish WebSocket connections, send messages, and receive responses in real-time.

What are WebSockets?

WebSockets provide a persistent, full-duplex communication channel between a client and server. Unlike traditional HTTP requests that follow a request-response pattern, WebSockets maintain an open connection that allows both the client and server to send messages at any time.

WebSocket vs HTTP

Feature	HTTP	WebSocket
Connection	Request-Response	Persistent
Latency	Higher (connection overhead)	Lower (persistent connection)
Data Flow	Unidirectional	Bidirectional
Use Case	Traditional APIs	Real-time applications
Overhead	Higher per request	Lower per message
Complexity	Simple	More complex
