Domotz is built for cost-conscious MSPs who need monitoring, remote access, and basic network maps at a transparent price. Its main limitation: diagrams are secondary to remote access and monitoring. These are the best Domotz alternatives for network discovery, topology visualization, and living documentation, starting with the one we build, Scanopy.
The best Domotz alternatives

Scanopy vs NetBrain, head to head →SolarWinds Network Topology Mapper is for enterprise teams that standardize on Microsoft tools and need Visio-native network diagram exports.
Scanopy vs SolarWinds Network Topology Mapper, head to head →LibreNMS
LibreNMS is for teams with Linux skills that want free, self-hosted monitoring with basic topology visualization.
Scanopy vs LibreNMS, head to head →NetDisco
NetDisco is for network teams that want free, open-source Layer 2 topology discovery and device tracking.
Scanopy vs NetDisco, head to head →Faddom
Faddom is for enterprise IT teams mapping application dependencies for data center migrations and cloud transitions.
Scanopy vs Faddom, head to head →NetBox

Why Scanopy is a strong Domotz alternative
Domotz and Scanopy both run a single on-site collector and build a Layer 2 topology map with no endpoint agents, so for basic "what's on this network" mapping they overlap. They're built around different priorities, though. Domotz is a monitoring and remote-access platform — its headline value is monitoring, alerting, and secure remote connections into client devices, with network topology as a supporting feature. Scanopy is a dedicated documentation tool: it fingerprints services per host and produces four switchable views (L2, L3, workloads, applications), and it does no monitoring or remote access at all.
The decision usually comes down to scope and price. Domotz is cheap and transparently priced at $1.50/device/month, which is why MSP communities consistently cite it as the most reasonably priced monitoring platform and the go-to lower-cost Auvik alternative. But its pricing is per-device, so a 100-device site is about $150/month, and the mapping sits behind remote access and monitoring. Scanopy is flat monthly with unlimited hosts and has a commercial self-hosted edition or a free, self-hostable AGPL-3.0 Community edition. If you want monitoring, remote access, and a basic map in one affordable platform, Domotz is the stronger pick. If you want deep, exportable, multi-view documentation that sits alongside whatever monitoring you already run, Scanopy is — and the two coexist cleanly on the same network.
On views, Domotz's Layer 2 map is confirmed in its help docs and does the job; the L3/VLAN mapping shows up in its marketing but isn't documented as an actual view, and there's no documented host-to-VM or application view. Scanopy adds L3, workloads, and applications — but Domotz does the monitoring and remote access that Scanopy doesn't touch.
Frequently asked questions
What is the best alternative to Domotz?
It depends on what you rely on Domotz for. If you want automatic network discovery with living L2, L3, workload, and application views and per-host service detection, Scanopy is the closest dedicated alternative — flat pricing regardless of host count, plus a free, self-hostable Community edition. Domotz itself remains the better choice when you specifically need cost-conscious MSPs who need monitoring, remote access, and basic network maps at a transparent price.
Is there a free or open-source Domotz alternative?
Yes. Scanopy, LibreNMS, NetDisco, and NetBox are open-source (OSI-licensed). Scanopy's Community edition is free to self-host under AGPL-3.0 and produces the full L2, L3, workload, and application views; the paid plans add cloud hosting and support at flat pricing.
Why do teams look for a Domotz alternative?
The most common reason: diagrams are secondary to remote access and monitoring. Teams that need an up-to-date visual map of what is actually on the network — without standing up additional tooling — tend to compare dedicated documentation tools like Scanopy alongside Domotz.
