nifa

Cross-platform network inspection tool - a modern, read-only alternative to classic network commands.

Features

• List all network interfaces with detailed information
• Inspect a specific interface with full metadata (addresses, DNS, gateway, speeds, flags, stats)
• View routing tables (IPv4/IPv6)
• View neighbor table (ARP/NDP) with optional vendor (OUI) lookup
• Inspect open TCP/UDP sockets with process association
• Monitor live per-interface traffic statistics in a TUI
• Fetch your public IPv4/IPv6
• Display OS, kernel, proxy, permission capabilities, and default interface info
• Export view as JSON/YAML for automation

Supported Platforms

• Linux
• macOS
• Windows
