WebSocket

Capture, inspect, and break on WebSocket frames.

When a connection upgrades to WebSocket, MinPin switches to a passthrough relay that captures every frame while forwarding bytes unchanged. The WebSocket detail tab shows a live frame table with direction, time, type, length and a data preview, a detail view (pretty-printed JSON or a hex dump), All / Sent / Received filters, the Handshake, and a clear button.

WebSocket breakpoints (PRO)

With a breakpoint whose WebSocket type is enabled, MinPin pauses a complete data frame before relaying it. You can Continue (⌘↩; text frames can be edited first), Drop the frame (⌘⌫), or Abort the connection (⌘.). A paused frame continues on its own after 60 seconds.
