Connect to any WebSocket server, send and receive messages, test heartbeat and export logs
FAQ
How does the heartbeat check work and why does it show unresponsive?
Browsers cannot send protocol-level ping frames, so a text message "ping" is sent at intervals; after 30 seconds without any message the connection is marked unresponsive. Servers that never reply may look unresponsive while connected.
What are common reasons a connection fails?
Check the URL, whether the server is running and your network. From an HTTPS page the browser blocks insecure ws:// connections, so use wss:// instead. Logs are kept in page memory only and never uploaded.
