Debug WebSocket traffic in real-time. Decode binary/text frames and inspect protocol handshake headers.
Default echo server: echo.websocket.events (the old echo.websocket.org endpoint is retired).
A WebSocket frame viewer helps inspect WebSocket message frames, including their direction, payload, and type. It is useful for diagnosing real-time application communication.
Paste or load frame data, select a frame, and examine its payload and metadata. Compare inbound and outbound frames when tracing a conversation.
Do not expose production credentials, cookies, or private message payloads when sharing WebSocket diagnostics.
