Scanopy is for IT teams and MSPs who want a dedicated network diagram automation tool which works alongside their existing monitoring platform. ManageEngine OpManager is for mid-market IT teams that want monitoring and visualization at a lower per-device cost. The table below puts the two side by side on discovery, the four topology views, pricing, and licensing, so you can see where ManageEngine OpManager fits and where Scanopy does.

How they compare
OpManager and Scanopy overlap more than most pairings on this list. Both auto-discover L2 and L3 topology over SNMP, CDP, LLDP, and ARP, and — unusually — both produce a workload view: OpManager maps host-to-VM, VM-to-datastore, and host-to-network relationships through its virtualization maps, which matches Scanopy's workload view. The difference is the category. OpManager is a full monitoring platform (it happens to have unusually deep visualization, including rack and floor-plan views most monitoring tools lack), while Scanopy is a dedicated documentation tool with per-host service fingerprinting and no monitoring, alerting, or polling.
The trade-off is platform versus focus, and price. OpManager is self-hosted on Windows or Linux, is cheap (from about $95/year for 10 devices), scales to tens of thousands of devices, and bundles monitoring you may want anyway. Scanopy is flat monthly with unlimited hosts, self-hostable under a commercial license or free under AGPL-3.0, and adds an application-dependency view OpManager doesn't have. If you want monitoring plus strong built-in visualization at a low per-device cost, OpManager is the better fit. If you want documentation that's independent of your monitoring stack — and an application view — Scanopy fits alongside it. Monitor with OpManager, document with Scanopy.
OpManager keeps pace with Scanopy on L2, L3, and the workload (host-to-VM) view, and its rack and floor-plan views are something Scanopy doesn't offer at all. Scanopy pulls ahead in two places: the application-dependency view and per-host service fingerprinting. OpManager has no application-grouping map.
When to choose which
Choose Scanopy when: You want documentation tool over monitoring platform: 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 ManageEngine OpManager when: Mid-market teams that want monitoring and visualization in one tool at a lower per-device cost than Auvik. The visualization options (rack views, floor plans) are unusually good for a monitoring tool.
