Scanopy vs PRTG Network Monitor

Scanopy is for IT teams and MSPs who want a dedicated network diagram automation tool which works alongside their existing monitoring platform. PRTG Network Monitor is for teams already invested in the Paessler ecosystem who want built-in topology mapping alongside monitoring. The table below puts the two side by side on discovery, the four topology views, pricing, and licensing, including PRTG Network Monitor's trade-offs.

Scanopy vs PRTG Network Monitor: head to head

How they compare

PRTG and Scanopy both discover a network and draw maps, but they're built for different jobs. PRTG is a mature, sensor-based monitoring platform that's been around since 2003 with a large installed base; its maps exist to visualize what it monitors. It has no native automatic Layer 2/3 topology mapping, though — Paessler's own knowledge base states plainly that "PRTG has no way of knowing which switch is connected to which so creating an automatic graph is not possible", and the documented fix is the third-party UVexplorer add-on. Scanopy's entire job is automatic topology: one daemon produces four switchable views (L2, L3, workloads, applications) plus per-host service fingerprinting, out of the box and with no add-on.

So the trade-off is monitoring-first with bolt-on mapping versus mapping-first as the product. If you already run PRTG and mainly want monitoring, alerting, and traffic analysis — with maps as a secondary view — staying in PRTG (and adding UVexplorer if you need real L2 maps) avoids another tool. If accurate, automatic, shareable, multi-view documentation is the actual goal, Scanopy is built for that and doesn't need a separate discovery engine to produce a topology. Scanopy is flat monthly with unlimited hosts, self-hostable under a commercial license, or free under AGPL-3.0, and it sits alongside PRTG rather than replacing your monitoring.

PRTG is also a much broader and more proven monitoring platform than Scanopy — two decades of development, a huge sensor library, and an installed base Scanopy can't claim. For monitoring, it wins outright. This comparison is only about which tool draws the network map, and that's Scanopy's automatic topology, not PRTG's.

When to choose which

Choose Scanopy when: You want auto topology over sensor-based monitoring: 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 PRTG Network Monitor when: If you already use PRTG for monitoring and want basic topology visibility, the built-in maps avoid adding another tool. The maps show what PRTG discovers, which is thorough.
