Zui

Purpose: Zui is a desktop application for querying and debugging Zed lakes.
Data exploration: Zui is a graphical interface for exploring data in Zed lakes.
Ingest and query features: The product page lists drag-and-drop ingest, schema inference, named queries, and filters and pivots.
Preview and shape data: Zui lets users preview and shape data while loading it into a Zed lake.
Packet capture analysis: Bundled Brimcap generates Zeek and Suricata summary logs from packet captures, and Zui can extract packet flows.
Security integrations: Packet capture views can correlate Zeek events with Suricata alerts, and right-click options can query VirusTotal or whois.
Threat rules: By default, bundled Suricata applies Emerging Threats Open rules, which are updated when Zui launches while connected to the internet.
Local storage: Imported data is stored in a local Zed lake under the user's Zui data directory.
Remote lake support: Zui can connect to a remote Zed lake, whose service uses TCP port 9867 in the documented setup.
Security: The maker says Zui releases are signed with a code signing certificate to indicate the installer came from Brim Data and has not been tampered with since it was built.
Support: The installation guide directs users who need help to troubleshooting documentation and the public Slack community.
Platform requirements: The maker recommends Windows 10 or newer, macOS Ventura 13.7 or newer, Ubuntu 20.04 or newer, Debian 11 or newer, Fedora 31 or newer, or Rocky 9 or newer.
Notable limitation: The maker says Linux updates require manual uninstalling and reinstalling.
Maker status: Brim Data says it is currently developing SuperDB while continuing to publish legacy Zed and Zui releases and documentation.
