WebSocket Tester – Online WebSocket Client
The WebSocket Tester lets you connect to any WebSocket server, send messages, and view incoming messages in real time — all without installing any software.
How to use
- Enter a WebSocket URL (starts with
ws://orwss://) - Click Connect
- Type a message in the input box and press Send or Enter
- Received replies appear in the message log
Preset servers
Use the echo.websocket.org preset to test that everything is working — it reflects any message you send back to you immediately.
Connection stats
The stats panel tracks the total number of messages sent and received and the cumulative bytes transferred during the session.
