termshark vs Zui

termshark is a terminal interface for tshark, inspired by Wireshark, for inspecting packet captures and network traffic. It can read pcap files or sniff live interfaces when tshark is permitted, including on a remote machine where a capture need not be copied to a desktop. Users can apply Wireshark display filters, group conversations by protocol, and reassemble TCP and UDP streams. Packet search covers packet lists, structures and bytes, using text, regular expressions, hexadecimal input or display filters. The guide also describes importing a Wireshark column set when the configuration can be found, and transferring the current capture with Magic Wormhole. The project lists Linux, macOS, BSD variants, Android through Termux and Windows. It is free and MIT-licensed, and the project says its Go implementation builds as one executable on each platform. Packet analysis requires tshark 1.10.2 or higher in the user's PATH. The project notes that some tshark features are not yet exposed by termshark; the latest listed release is v2.4.0, dated July 11, 2022.

Zui is a free desktop application for exploring, querying, and debugging data in Zed lakes. It runs on Linux, macOS, and Windows, with drag-and-drop ingest, schema inference, named queries, filters, and pivots. Users can preview and shape data while loading it; imported data is stored locally under the Zui data directory, and the application can also connect to a remote Zed lake.

For packet capture analysis, bundled Brimcap creates Zeek and Suricata summary logs, and Zui can extract packet flows. Packet views can correlate Zeek events with Suricata alerts and offer right-click queries to VirusTotal or whois. Bundled Suricata uses Emerging Threats Open rules by default and updates them when Zui launches while connected to the internet. The maker says releases are signed with a code signing certificate to indicate the installer came from Brim Data and has not been changed since it was built. Brim Data continues to publish legacy Zed and Zui releases and documentation while developing SuperDB. Linux updates require manually uninstalling and reinstalling; the installation guide points users to troubleshooting documentation and a public Slack community.
