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, opcode, size, and a JSON/hex detail view, plus text/binary filtering and a clear button.

WebSocket breakpoints

With a breakpoint whose WebSocket type is enabled, MinPin pauses a complete data frame before relaying it. You can forward it (optionally edited), drop it, or abort the connection. Protobuf frames can be decoded and edited before resuming.
