The best Network Diagram Software, Topology Software & Mapping Tools

What should you look for in network topology mapping tools? 

We reviewed the market for network diagram and mapping software and analyzed options based on the following criteria:

  • An autodiscovery system that lists all devices on the network
  • A switch port scanner that identifies how all devices connect together
  • A recursive scan that constantly rechecks the network
  • A network device inventory
  • A dynamic mapping tool that creates a topology diagram from network inventory data
  • A free trial or a demo service that enables you to test the software before buying it
  • Value for money from an automated network discovery and documentation tool

With these selection criteria in mind, we identified a group of network diagramming and topology mapping systems that offer time-saving insights into the network layout.

Some of these software packages even automatically update your network topology map when new devices are added or removed from the network, which really cuts down on manually having to remove them yourself.

Below you will find an extensive list of the Top (some of which are FREE) Network Diagram Software packages available for download and trials.

A brief overview of the software is listed below to give you a better understanding of what it is capable of doing.

1. Auvik – FREE TRIAL

Auvik ITAM Documentation

Auvik is a cloud service that offers network monitoring and management. At the heart of the Auvik system is a network discovery and topology mapping service. As it is hosted in the cloud, the Auvik system isn’t restricted to one site. It can map any network anywhere as long as you give it access.

Key Features

  • Cloud-based
  • Network discovery
  • Topology mapping
  • Network monitoring
  • Network management tools

Why do we recommend it?

Auvik includes an autodiscovery routine that enables the package to assemble a network map. This SaSS package is delivered from the cloud and so able to map any network that you install its data collector on. The tool also assembles a network inventory, which provides details on each mapped device.

Another advantage of the cloud location of this software package is that it can be accessed from anywhere. This enables large businesses to centralize their network monitoring service and small businesses to let a single network technician track performance while away from his desk. The dashboard can be accessed from any device that has an internet connection.

The initial scan of the network creates a device inventory. This forms a menu for ongoing device monitoring and it is constantly updated.

The network topology map is drawn up automatically from the device information contained in the inventory. So, when a change occurs on the network, it is reflected in an updated inventory and a redrawn topology map.

The mapping services in the Auvik package can draw up plans at Layers, 1, 2, and 3, so you can flip between physical, switch-level, and router-level views of your system. Protocol analysis provides you with activity graphs that are segmented by application. See what are the major traffic generators and get an idea of where you can cap resource availability and share out the network more equitably. Identify interactive services and prioritize them with queueing to ensure a decent quality of service for VoIP and video streaming.

Auvik is a SaaS platform that is delivered from the cloud so its dashboard can be accessed from anywhere through any standard Web browser and it will document and map any network to which it is granted access.

Who is it recommended for?

This cloud-based system is available in two editions and both will map an unlimited number of networks, which means that the type of business that would get the best value for money from this package would be a multi-site organization or a managed service provider. Unfortunately, Auvik doesn’t publish its prices.


  • Remote access to networks from the cloud
  • Autodiscovery of network devices
  • Network topology mapping
  • Continuously updated inventory and map


  • No software inventory features

Auvik is available in two editions, Essentials and Performance. The Performance plan has more features and so is more expensive. However, Auvik doesn’t publish its price list, so you have to contact the company and request a quote. Get a 14-day free trial.


Auvik is our top pick for network diagram, topology, and mapping software because it offers three layers of views in its automated mapping processes as well as the live creation of a network inventory. See details of each device and instantly understand how that device slots into the network. Get traffic data as well so that you can seal with applications that hog all of the bandwidth and prioritize interactive services.

LanFlow is priced at $99 for a single license, with discounts offered for purchases of multiple licenses.

14. Network Notepad

Network Notepad Diagramming Software

Network Notepad (FREE) is just as the name of the software implies, a program for creating interactive diagrams of networks and their components.

This tool has a great add-on worth mentioning called “CDP Neighbor Tool” (Cisco Discovery Protocol), which is a function that will pull information from the CDP table of a selected Cisco device that has CDP enabled and draw and map out the network components based on that table.

Key Features

  • Graphics editor
  • Networking icons
  • Multi-user collaboration

Why do we recommend it?

This is a lightweight system in free and paid versions. None of the versions has an autodiscovery function but you can get a free add-on that implements the Cisco Discovery Protocol (CDP) that works with all editions. One problem is that only Cisco uses this discovery protocol but there is a compatible protocol called the Industry Standard Discovery Protocol (ISDP) that Dell and Netgear use.

Fully scalable using vector-based graphics, zooming in and working on a granular level is a pleasure with no pixelated resolution and can create “Custom Shapes” for your devices within the software.

The interface of the software feels like Microsoft Word 2003 interface, with no ribbon menu as some of the other software we have reviewed.

Who is it recommended for?

There are three editions of Network Notepad: Free, Professional, and Enterprise. None of the versions include an autodiscovery service, and the discovery add-on isn’t guaranteed to work with all brands of network devices. So, you would use this tool to design or document a small network.


  • Supports two versions, one for network mapping and another for simple charting
  • Barebones interface makes this a lightweight and clutter-free tool
  • Supports in-depth networking details like VLANs, subnets, and address pool


  • Only available for Windows
  • Only uses ping to discover devices

The FREE edition of the software is compatible with Microsoft Windows 9x, NT, 2K, XP, and Vista, but does not specifically mention support for Windows 7, 8.1, or 10. However, the Professional version is compatible with all newer Microsoft versions, including Windows 10, 8, 7, Vista, XP, and 2000, which is an important consideration for downloading. The software is available in a Free version, and the Professional Version is priced at £16 GBP per license.

15. Microsoft Visio

Microsoft Visio Diagraming LAN/WAN Network

Microsoft Visio is probably the most well-known network mapping and layout software among Business & IT professionals alike.

The package is available for subscription with two plans that are priced at $5 per month and $15 per month when paid annually. A perpetual license costs $369.99 for Visio Standard 2021 or $719.99 for Visio Professional 2021.  Many of the software packages we reviewed above have built their interfaces around Microsoft's popular Ribbon and Menu systems.

Key Features

  • Graphics editor industry leader
  • Network icons
  • Topology templates

Why do we recommend it?

Microsoft Visio is the leader of the pack in charting software. However, it is also the most expansive. You don’t get a discovery service with this tool but its proprietary file format is the industry standard and you can find many network discovery systems that will discover a network and draw up a map that you can import into Visio to make adjustments.

The newer versions of Visio now have added functionality that allows people to comment on your Diagrams through either Visio itself or through a Browser (using Sharepoint) and even goes as far as built-in Instant messaging using either Microsoft Skype for Business or Lync.

Bundled into the software are over 70 pre-built templates and thousands of Shapes, including IT focused elements that represent Active Directory components, as well as detailed network components and Network appliances and routes.

Visio also has shapes and components for Datacenter, help desk, HVAC layouts, Enterprise and Home network diagramming and many more options.

It's truly a fully featured diagramming tool for not only business professionals, but for IT professionals who need serious diagramming capabilities.

One downside to Visio is the inability to scan Networks and automatically populate your diagram for you natively, although you can do this with an add-on for Microsoft Baseline Security Analyzer called Visio Connector, which can be used to scan your network and view the results in a fairly thorough Visio diagram.

Who is it recommended for?

This is a high-end tool and will appeal to large businesses. The subscription plan removes the high upfront cost of using the system and can make the tool more accessible to smaller businesses. However, companies on tight budgets could save money by using one of the other tools on this list that can import and export Visio files.


  • Easy to use, part of the Microsoft Suite
  • Good for network planning and theoretical designs
  • Widely used file format


  • Only available in Windows
  • Lacks live network auto-discovery builtin (The plug-in is no longer supported)
  • Fairly expensive when compared to its competitors

Visio offers several pricing options, including Visio Standard 2021 for $369.99 and Visio Professional 2021 for $719.99. There are also subscription plans available at $5 or $15 per month.
