TCP Viewer as a TShark alternative for Mac

TCP Viewer and TShark both use Wireshark protocol analysis. TCP Viewer presents the results in a native Mac interface, while TShark exposes Wireshark analysis through the terminal.

TCP Viewer vs TShark

TCP Viewer	TShark
Interface A visual macOS app with packet, protocol, stream, application, and domain views.	Interface A command-line analyzer that prints packets and selected fields.
Filtering Supports Wireshark display-filter expressions alongside quick visual filters.	Filtering Supports Wireshark capture and display filters through command options.
Packet details Links decoded protocol fields to highlighted ranges in the raw packet bytes.	Packet details Prints protocol trees or selected fields as terminal output.
Streams Follows TCP and UDP streams in a dedicated visual window.	Streams Can produce stream and statistical output through command options.
Traffic organization Groups packets by application and domain for interactive investigation.	Traffic organization Extracts fields and statistics for pipelines, scripts, and text processing.
Automation Its bundled CLI starts captures and controls the desktop app. TCP Viewer Pro also supports MCP.	Automation Runs as a standalone process in scripts, CI jobs, and remote shells.

Choose TCP Viewer when

• You want to browse and correlate packets visually.
• You need application or domain grouping on your Mac.
• You want protocol fields, bytes, and streams linked in one interface.
• You use familiar Wireshark display filters but prefer a focused desktop app.

Choose TShark when

• You need structured or selected fields in a shell pipeline.
• You run analysis on a remote or headless machine.
• You want a standalone command for repeatable batch processing.

Because both tools understand Wireshark display filters and standard capture files, you can use TCP Viewer for visual triage and TShark for repeatable extraction or batch analysis.
