Frequently Asked Questions

What is the difference between WS and WSS?
WS (ws://) is unencrypted WebSocket, while WSS (wss://) is encrypted with TLS/SSL, similar to HTTP vs HTTPS. Always use WSS in production.
Can I test binary WebSocket messages?
This tool focuses on text-based messages. Binary messages will be shown as [Binary data] indicators.
Why does my connection fail?
Common reasons include CORS restrictions, invalid URLs, server not running, or firewall blocking WebSocket connections.
