LanTopoLog vs NetK

LanTopoLog discovers, maps and monitors physical network topology on a local network. It uses agentless SNMP discovery and presents a searchable, editable map; the maker says it works with any switch model. Its Switch Port Mapper links physical ports to attached devices’ MAC and IP addresses. Monitoring includes traffic, invalid packets and dropped packets, with threshold alerts sent by email, Telegram or Syslog. Reports export to PDF and Draw.io/Diagrams.net. Browser access and remote control are supported, but publishing requires an external web server. The product is listed for Linux, Windows and web use, though Linux has limited functionality. LanTopoLog 2 costs 50.00 USD once for one local network; the license covers up to three bound switches and cannot be renewed. Discovery may miss connections. After some time, the unregistered version disables web publishing, VLAN IDs, traffic charts and search, and shows demo data. A free plan and trial are listed.
