WebSocket Tester

Connect to ws:// and wss:// endpoints, send messages, watch frames stream in

WebSocket connections go directly to your server

Why: The browser opens a WebSocket connection to the URL you enter.

Data sent:

WebSocket URL and subprotocols, messages you send, and browser-controlled handshake metadata

Data handling: The destination receives the connection and messages, including cookies the browser permits. Traffic does not pass through the app proxy; received messages remain in page memory.
