Frequently Asked Questions
What is a WebSocket client?
A WebSocket client connects to a WebSocket server and enables real-time, bidirectional communication. Unlike HTTP, the connection stays open for continuous message exchange.
What is the echo server?
wss://echo.websocket.org is a public test server that echoes back any message you send. It is useful for testing WebSocket connections.
Can I send JSON messages?
Yes. Type or paste JSON in the message input and it will be sent as-is. Received JSON messages are automatically formatted for readability.
Is the connection secure?
Connections using wss:// are encrypted with TLS, just like HTTPS. The WebSocket connection runs directly from your browser -- no data is proxied through our servers.
