Netvis - Visual Packet Map

Description

Transform static packet captures into a living, interactive network map. Netvis turns complex .pcap and .pcapng data into intuitive, animated topology graphs. Designed for students, IT administrators, and security professionals alike, Netvis eliminates the need for complex command-line tools and cryptic terminal filters, delivering instant visual clarity to network traffic analysis. Simply open a capture file to automatically discover hosts, map connection flows, and replay network events on a fluid, interactive timeline. KEY FEATURES * Annotations: To make your analysis experience easier, Netvis allows you to add time-bound shapes, arrows, text and highlighting to the traffic. These don't modify the capture file. * Automatic Topology Mapping: Watch Netvis instantly group packets into clear connections and arrange hosts in an optimized, readable layout. The most connected devices are automatically centered, saving you hours of manual sorting. * Interactive Timeline Replay: Play, pause, scrub, or speed up your capture. Watch color-coded packet indicators move dynamically along connection edges to see exactly when and how data flowed. * Smart Host Discovery: Netvis automatically enriches host nodes with real-world context by parsing DHCP hostnames, mDNS local names, and identifying manufacturers using built-in MAC OUI lookups. * Deep Layer-7 Packet Inspection: Click any host or packet to explore information about host or nested protocol layers (Ethernet, IPv4, ARP, TCP, UDP, ICMP, DNS, DHCP, HTTP, TLS and more) alongside a hex viewer. * Automated Anomaly Detection: Instantly surface critical network events without manual filtering. Netvis automatically flags port scans, host sweeps, DNS bursts, packet floods, and large downloads right upon import. * Persistent Customization: Save your host renames and custom device tags securely to your Mac, allowing your network profiles to persist across sessions and new captures.

This update: - add annotations - it's now possible to add text, arrows, shapes to the capture as well as highlight hosts for even better analysis experience. - adds parsers and support for a few protocols (IPv6, NTP, etc). - fixes and properly handles broadcast and localhost connections. - adds caching of graph state to save assigned host names and arrangement (cache is in-app and doesn't touch the file). - adds new Netvis project format which stores state alongside the original capture file while maintaining integrity. - adds standalone expanded packet and host inspector windows. - fixes stuttering while resizing inspector and bottom panes. - polishes other parts of the interface.
