LanTopoLog vs Scanopy

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.

Scanopy discovers and documents network hosts, services, and topology from scans. It produces Physical (L2), Logical (L3), Workloads, and Applications views, then refreshes documentation on a schedule rather than continuously polling. Discovery uses a single daemon on the network, with no agents required on individual endpoints. Listed integrations include Docker, Podman, Instant On, UniFi Controller, gNMI, and SNMP; Instant On and gNMI are marked beta. Depending on the plan, diagrams and data can be exported or shared in formats including PNG, SVG, HTML, PDF, Mermaid, Confluence, and CSV. API access is listed for paid plans, and the API has a limit of 300 requests per minute. The self-hosted, open-source Community Edition has no time restriction and is limited to one network and one seat. Paid plans start at $11.99 a month billed yearly. Scanopy documents assets and connections, but is not a replacement for monitoring device health, bandwidth, or alerts.
