# Overview

<Info>
  WebSocket support is available from Bruno 2.13.0.
</Info>

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                  |
