Scanopy is for IT teams and MSPs who want a dedicated network diagram automation tool which works alongside their existing monitoring platform. NetBrain is for large enterprises that need network maps integrated with automation and troubleshooting workflows. The table below puts the two side by side on discovery, the four topology views, pricing, and licensing, including NetBrain's trade-offs.

How they compare
NetBrain and Scanopy answer different questions. NetBrain is an enterprise network-automation platform: its dynamic maps cover L2, L3, virtualization (ESXi/vSwitch/VM), and application-path mapping, and they tie into troubleshooting runbooks and automation playbooks, so a map can trigger actions, not just display data. It is built for large, complex networks with thousands of devices and a team to run it. Scanopy is a focused documentation tool: it discovers your network and produces four switchable views (L2, L3, workloads, applications) plus per-host service fingerprinting, and it stops there. No automation engine, no runbooks.
The trade-off is scope, price, and effort. NetBrain is enterprise-priced (contact-sales only) and complex enough that a proper proof-of-concept is essential. Community experiences are polarized: some teams get excellent results, others have struggled with map accuracy for years. Scanopy is flat monthly with unlimited hosts, self-hostable under AGPL-3.0, and runs from one daemon with no platform to administer. If you need maps wired into operational automation across a large enterprise, NetBrain is the category leader and Scanopy is not a substitute. If you want accurate, living, shareable network documentation without standing up an automation platform, Scanopy is simpler and far cheaper.
Honest note on capability: NetBrain is one of the few tools here that genuinely produces all four view types, so on view coverage alone it matches Scanopy. The difference is everything around the map, not the map itself.
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 NetBrain when: Large, complex networks where diagrams aren't just documentation but part of the operational workflow. NetBrain handles networks with thousands of devices and integrates maps directly into troubleshooting runbooks and automation playbooks.
