const ws = new WebSocket('wss://echo.websocket.org');
ws.onopen = () => ws.send('Hello');
ws.onmessage = (e) => console.log(e.data);

PYTHON

import asyncio
import websockets
async def test():
  async with websockets.connect('wss://echo.websocket.org') as ws:
    await ws.send('Hello')
    print(await ws.recv())
asyncio.run(test())

Troubleshooting Checklist

✅ URL must start with ws:// or wss://
✅ Check CORS/Origin policies on your server.
✅ WSS requires a valid SSL certificate.
✅ Use Browser DevTools (F12) Network tab.

WebSocket Online Simulator | Free WebSocket Testing Tool

WebSocket Architect is a powerful, free online WebSocket client designed for developers to test and debug real-time communication protocols. Whether you are building a chat application, financial ticker, or live gaming platform, our tool provides a seamless environment to connect to wss:// and ws:// servers. We support a wide range of message formats including plain text, JSON, and hexadecimal data.

Comprehensive Features for Professional Debugging

Our online WebSocket debugger includes features like automatic JSON formatting to make complex data readable. For low-level protocol testing, the hex mode allows you to send binary data as hexadecimal strings. The connection history feature stores your recently used endpoints locally, so you don't have to re-type long URLs. We also provide a latency display to show you how long the handshake takes in milliseconds.

How to Use the WebSocket Client

Input URL: Enter your server endpoint. Example: wss://echo.websocket.org.
Establish Connection: Click the 'Connect' button. Our tool will attempt a handshake.
Monitor Logs: Once connected, all incoming and outgoing packets are timestamped in the log area.
Send Messages: Use the transmit box to send data. Use JSON formatting for better readability.

Developer Code Examples

Developers often search for "how to connect to websocket in javascript". Here is the snippet:


            const socket = new WebSocket('wss://your-server.com');
            socket.onopen = () => { console.log('Connected!'); socket.send('Ping'); };
            socket.onmessage = (event) => { console.log('Message received:', event.data); };
            socket.onclose = () => { console.log('Socket closed'); };

Frequently Asked Questions (FAQ)

Why does my WebSocket connection fail?

Common issues include incorrect URL syntax, mixed content blocking (trying to connect to ws:// from an https:// site), or missing cross-origin (CORS) headers on the server side. Always check your browser's console for specific network errors.

Does WebSocket Architect support binary data?

Yes, we support hexadecimal input which is automatically converted to binary for transmission, ideal for IoT and firmware communication testing.
