Ctrl+Enter to send
Enter a ws:// or wss:// URL and click Connect. Send messages with the text box above; received messages are logged with timestamps. Legend: ↑ sent (blue), ↓ received (green), · system (gray), ✗ error (red). Note: browsers block insecure ws:// from https:// pages — use wss:// when this page is served over HTTPS. A good public test endpoint is wss://echo.websocket.org (echoes whatever you send).
