DeviceShelf maps your local network and keeps the map on your own machine. One scan lists every device that answers: vendor, hostname, operating system, device type. It also shows which ports are open and what that means for your security.
It sweeps every adapter at once, identifies devices from MAC OUI, DNS, mDNS/Bonjour, NetBIOS, TTL and DHCP fingerprints, enumerates open TCP and UDP ports with service detection, and writes a prioritised security report: exposed Telnet, RDP, ADB, Docker API or Redis, default credentials, weak TLS and known-CVE hints, each with a fix and a risk score from 0 to 100. In the background it watches who joins and leaves, with uptime, latency and live bandwidth per device.
No account, no telemetry, no cloud sync. Scan results stay on the computer that produced them, and the optional AI assistant runs on your own API key or a local model. One licence covers desktop, mobile and the round-the-clock server edition.
