WebSocket Echo Tester
Connect to any public ws:// or wss:// endpoint, send text/binary frames, watch the response.
About this tool
A minimal WebSocket client: enter a ws:// or wss:// URL plus optional subprotocols, send text or hex-encoded binary frames, and watch the conversation in a timestamped log. The connection auto-closes after 60 seconds or on demand. Public hosts only — loopback and private addresses are refused.
