Best Network Documentation Tools

The aim of a technical documentation is to ensure that your users can flawlessly access your product and are able to use it with no problems. The network documentation tool helps you do exactly that. If a user cannot understand the instructions well and quickly, he may end up giving up on your product.

Network documentation tools have become necessary as the network applications that support the network architecture have become complex. The network administrator must somehow be made aware of the intricacies of those applications to better manage and support those applications. Network documentation tools are one way to accomplish this task. So what are some best network documentation tools? We will answer that in this article.

If you are looking for best tools to create and manage your software documentation, this post will be of great help. I have prepared a list of 12 top network documentation tools that can help you in every step of documentation process – writing documentation, creating interactive documentation or facilitating user’s onboarding with help of network application.

Confused about which network documentation tools are the best? I was too. The truth is, there are so many network documentation tools these days its no wonder we’re lost. This is why we created this list of best network documentation tools to help you make the right buying decision.

What should you look for in network mapping tools

We reviewed the market for network diagram topology software and analyzed the tools based on the following criteria:

  • A range of options that include monitoring tools and graphics editors
  • The ability to demonstrate different device types with specific icons
  • The option to amend generated network maps
  • Layout options, such as connections, site, and world views
  • Export capabilities to integrate layout images into presentations and documents
  • An opportunity for a cost-free assessment through a free trial or a demo system
  • Value for money that is provided by a tool that has additional capabilities

With these selection criteria in mind, we have assessed available network mapping tools, including software for all the major operating systems.

6. Faddom – FREE TRIAL

Faddom is an on-premises software package that performs a range of discovery and mapping functions. It can be used to create network topology maps and application dependency maps.

The discovery process creates an asset inventory, listing details of each encountered device. That inventory forms the reference base for a topology mapper in the package. Each node on the map is clickable and leads through to the device details page.

The discovery process repeats automatically and so spots any changes made to the network. Those changes get reflected in the inventory, which automatically updates the network topology map. The map can also be used for ongoing system monitoring. The service provides live statuses on device health and network traffic flows.

Compatibility: The software bundle for Faddom includes a custom VM, so it can run on any operating system as a virtual appliance.


  • Can be used for network mapping or for identifying application dependencies
  • Provides a console for live network performance monitoring
  • Includes network traffic flow monitoring

7. ConceptDraw Pro – best features overall

ConceptDraw Pro is a very versatile Business diagramming and drawing tool that doubles as a network diagram tool as well.

The software’s interface is very familiar to that of Microsoft Word 2007 in terms of button layout and menus.via

Because of its extensive menu and icon layout, it is Very Easy to use due to its Drag-n-Drop functionality, making this software easy to learn and use on a daily basis with very little training.

What are the different types of network diagrams?

There are two types of network diagrams. These are physical and logical. A physical network diagram shows the hardware in the network and how it connects together. A logical network diagram is a schematic that can include non-fixed links, such as “the internet” represented as a straight line.


There is no denying the fact that creating an API documentation tool is one of the most challenging paths in programming. This is because you need to understand how to read other people’s code, how to look at all the layers of a program and then merge in the new ones that you have created for your installation. Additionally, you also need to be able to simplify and organize this information, so that others can use it. This adds up to quite a complicated situation where carrying out, managing and inspecting all the nitty-gritty details becomes a daunting task.

Network documentation is the practice of keeping a record of changes, such as hardware or software, to a computer network. This may be in the form of network diagrams or flowcharts that document physical or logical network elements or data information flow, respectively.
