WebSocket Tester
Connect to any WebSocket server and send and receive messages in real time. Perfect for testing chat servers, live feeds and APIs. Everything runs in your browser — no data is sent anywhere else.
How to use
- Enter a WebSocket URL starting with
ws://orwss://and click Connect. - Wait for the status to turn green (connected).
- Type a message and click Send (or press Ctrl + Enter). Replies from the server appear in the log below, newest at the bottom.
- Click Disconnect when you are done testing.
Note
This tool can only connect to servers that accept WebSocket connections from your browser. If a connection fails, the server may be offline or may be blocking browser connections (CORS policies do not apply to WebSockets, but firewalls do). For a quick test, the default echo server simply sends back whatever you send it.
