NetfoxSee every device on your network with complete privacy and zero cloud dependency

Netfox

Netfox is a native macOS network scanner that gives you complete visibility into every device on your home network. Built with SwiftUI for macOS 15+, it delivers real-time monitoring, device history, and security insights without requiring cloud accounts or sending your data anywhere.

Product Highlights

• Multi-Source Discovery: Combines Bonjour, ARP, SSDP, NetBIOS, and active probing to detect Apple devices, smart TVs, IoT gadgets, and quiet hosts in one unified list.
• Risk-Aware Security Scanning: One-click scan checks 20+ common home-network ports (SSH, RDP, VNC, SMB, etc.) with plain-English explanations of each finding.
• Complete Device History: Tracks first seen, last seen, every online/offline transition, and all IP/hostname/vendor changes across app launches.
• Smart Alert System: Five alert types including new devices, returning devices, risky arrivals, port changes, and new services with per-device mute options.
• Privacy-First Design: No cloud, no account, no telemetry. All data stays on your Mac with one-keystroke Demo Mode for safe screenshots.
• Native macOS Experience: Built in SwiftUI with Universal Binary support for Apple Silicon and Intel, following system appearance and supporting keyboard shortcuts.

Use Cases

• Home Network Monitoring: Instantly see every connected device, when it joined, and its current status without logging into router admin pages.
• Security Auditing: Identify open ports and potential vulnerabilities on your own devices before attackers do.
• IoT Device Management: Track smart home gadgets, detect unauthorized connections, and monitor device uptime history.
• Network Troubleshooting: Use Wi-Fi diagnostics and device timelines to diagnose connectivity issues and performance problems.
• Privacy-Conscious Network Admin: Maintain complete network visibility without surrendering data to cloud services or vendor lock-in.

Target Audience

Netfox is designed for macOS users who want professional-grade network visibility without complexity—ideal for privacy-conscious homeowners, IT professionals working from Macs, and anyone managing smart home devices who refuses to trade security for convenience.
