Scanopy — Continuously generated L2/L3, workload, and application diagrams from network discovery

OSS health 93
About these scores

Discovery score is an unbounded weighted, log-compressed index of stars, watchers, forks, and contributors. Growth momentum is its change over the observed period; OSS health is a 0–100 score from available repository recency, Community Health, and release data.

Overview

Scanopy periodically scans infrastructure through one or more daemons and continuously maintains four views: L2 physical topology, L3 logical topology, workloads, and application dependencies. It combines SNMP, LLDP, ARP, and Docker discovery with SVG/Mermaid/Confluence export and shareable live maps. The latest release checked is v0.17.16.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Generate four topology views from the same discovery model

Scanopy discovers hosts and services and derives switch/port/link L2 topology, subnet/host L3 topology, bare-metal-to-container workloads, and service dependencies grouped into applications. More than 230 service definitions support automatic detection.

Extend discovery across sites and VLANs with distributed daemons and network protocols

Daemons can be deployed across segments for distributed scanning. SNMP, LLDP, and ARP cover network infrastructure while Docker integration adds containerized services. RBAC and shareable live views let network, DevOps, and MSP teams use the same current model.

For homelabs, enterprise networks, and MSP inventories that outgrow hand-maintained diagrams

It fits environments where out-of-band changes and drift make static diagrams unreliable. The strongest use case is continuous discovery feeding documentation or an existing source of truth, rather than manual diagram creation.

Sources: [2]

Design scan permissions and frequency carefully, and understand the AGPL/commercial licensing options

Discovery requires network reachability and potentially SNMP credentials, so production deployments should restrict scan scope, frequency, and credential privileges. The self-hosted code is AGPL-3.0, with a separate commercial license offered for organizations that cannot comply. As a 0.17-series project, upgrades should be tested and backed up.

Supplemental curator note

Treat Scanopy as a discovery and documentation layer that continuously models the real network, rather than merely as a diagram editor replacement.
