It runs a server and one or more daemons (dockerized) that scan VLANs via ARP and full 65k-port scans, detect 200+ common self-hosted services through pattern matching, poll network devices via SNMP v2c (including LLDP/CDP neighbor data), and generate an interactive, self-updating topology map. Features include versioned and branchable topologies, editable visualizations, CSV export, a granular API with scoped keys, and a UI for manually assigning unidentified ports.
