Know what is on your Wi-Fi

Discovery, assessment and capture in one app, with no setup.

Device Discovery

Bonjour/mDNS (DNS-SD) and SSDP find AirPlay receivers, printers, file shares, smart TVs and gateways. Optional /24 scans catch quiet services, and OUI lookups name the manufacturer.

Security Assessment

Flags risky exposed services and checks each manufacturer against CISA's Known Exploited Vulnerabilities catalog and the NVD. Findings export as a plain-text report.

Packet Capture

See DNS and SNI as they happen, with a local packet tunnel and no remote server. Export to pcap and open it in Wireshark.

TLS Inspection

A local HTTPS proxy that decrypts and logs HTTPS traffic for analysis, with your consent and on your device.
