KozBon

Discover, broadcast, and understand every Bonjour service on your network — with AI-powered insights built in.

KozBon scans your local network in real time and shows you every Bonjour (mDNS/DNS-SD) service nearby: printers, smart-home devices, media streamers, development tools, and more. Tap any service for full details — hostnames, IP addresses, ports, and TXT metadata — or long-press for an AI-generated explanation of what it does and why it's on your network.

AI-POWERED INSIGHTS — YOUR CHOICE OF ENGINE

• Chat: Conversational assistant grounded in your live network — ask about discovered services, what they do, and how your network is configured
• Choose your AI backend in Settings:
