termshark review
A focused terminal analyzer for interactive PCAP and live traffic inspection.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
termshark is an open-source, terminal-based interface for tshark and Wireshark-style packet analysis. It is suited to network engineers, incident responders, and developers who want interactive inspection of PCAP files or live traffic from interfaces. The application displays packet lists, protocol structures, hexadecimal data, network conversations, and reassembled TCP or UDP streams. It runs from the command line across Windows, macOS, Linux, and Android through Termux, with deployment for both local and remote environments.
Its strongest fit is an interactive workflow built around established packet-analysis concepts. Users can apply Wireshark capture and display filters, search packet lists, structures, bytes, and display-filter results, and copy packet-data ranges from the terminal. Stream reassembly and conversation views add flow-level context, while command-line and tshark pass-through operation support workflows that move between direct commands and the interface. Integration with tshark and Wireshark makes it a focused front end for users already working with that ecosystem.
The trade-off is its terminal-first design and dependency on tshark for packet-analysis functionality. That makes termshark a practical choice for command-line troubleshooting, local or remote inspection, and users who prefer text-based tools. It is less suitable for teams seeking a graphical packet-analysis workspace or a product centered on a broader visual monitoring experience. Buyers should choose termshark when PCAP handling, live capture, filtering, stream inspection, and terminal operation are the priority; those wanting a graphical interface should consider an alternative.
termshark pros and cons
- Where it wins
- Reads PCAP files and captures live traffic from interfaces
- Supports Wireshark capture and display filters
- Reassembles TCP and UDP streams with conversation views
- Where it doesn't
- Depends on tshark for packet-analysis functionality
- Uses a terminal interface rather than a graphical workspace
- Advanced packet analysis requires familiarity with filters and tshark
