Scanopy is for IT teams and MSPs who want a dedicated network diagram automation tool which works alongside their existing monitoring platform. Faddom is for enterprise IT teams mapping application dependencies for data center migrations and cloud transitions. The table below puts the two side by side on discovery, the four topology views, pricing, and licensing, including Faddom's trade-offs.
Scanopy vs Faddom: head to head
| Scanopy | Faddom | |
|---|---|---|
| DiscoveryProtocols used to find devices and map connections | SNMP LLDP CDP ARP TCP/UDP | NetFlow/sFlow [23] |
| Service detectionWhether the tool fingerprints services per host (databases, web servers, containers) beyond simple port detection | Yes 240+ types | Basic app dependencies [23] |
| Network ViewsWhich topology views the tool produces from discovery. L2 Physical switch ports and links L3 Subnets, VLANs, routing Workload VM/container host nesting Application Service-dependency / app grouping Yes supported Tag ? unverified Greyed not supported | Application view is automatic, inferred from observed traffic (NetFlow/sFlow); does no network-layer L2/L3 topology. [23] | |
| Live updatesWhether the map updates automatically after the initial scan | Yes | Yes |
| Open sourceOSI means an OSI-approved open-source license; Source available means restricted; No means proprietary | OSI AGPL-3.0 | No |
| PricingStarting price or pricing model | Starts at $11.99 monthly, unlimited hosts | Free up to 50 servers then from $19,000/yr [24] |
| Also includesCapabilities beyond network diagramming | Docker Visualization | — |
When to choose which
Choose Scanopy when: You want a dedicated, living network-documentation tool: automatic L2, L3, workload, and application views, per-host service detection, flat pricing regardless of host count, and a free self-hostable Community edition. It sits alongside your monitoring stack rather than replacing it.
Choose Faddom when: Mid-to-large enterprise IT operations teams planning migrations or cloud moves who need an automatic picture of application dependencies without deploying agents. The public pricing and 50-server free tier make it genuinely evaluable without a sales process, which is unusual for ADM.

Started as a homelabber, now deep in SNMP MIBs, Layer 3 topology, and service fingerprinting - building the network documentation tool I wished existed.
