WebSockets
Test and debug WebSocket connections with an intuitive interface.
What are WebSockets?
WebSockets provide a persistent, bidirectional communication channel between a client and server. Unlike HTTP, which is request-response based, WebSockets allow real-time data transfer in both directions.
Our WebSocket tool lets you connect to any WebSocket server, send messages, and view responses — all from your browser. It's perfect for testing APIs, debugging connections, and learning WebSocket protocols.
