- Monitors WebSocket frame exchanges with message timeline details.
- Auto-indents and prettifies JSON payloads for both requests and responses.
- Allows exporting captured session history directly to standard HAR files.
- Provides one-click formatting tools (cURL commands, Python requests scripts) for easy copy-pasting.
