Best Technical Documentation Tools

I only have one question for you: do you know the best free documentation tools? I mean, do you know for sure? You are a software developer or a web developer or an app developer or a mobile application developer. Write your code; build your product; develop your application. But do you ever stop to think about how to improve software documentation? I’m going to cover some options that can help you with that.

One sure way to make the process of creating, publishing, and maintaining technical documentation even more tedious is to use a half-baked technical documentation software. Documentation allows non-technical personnel to learn, use and support a product as efficiently as possible. There are many factors you should consider when selecting a documentation tool including: platform, cost and scope of your project. While all of these factors vary, the software documentation tools tend to fall into the same categories. When evaluating a selection of the best software documentation tools for your project, keep in mind that you’ll want to choose one that works with your requirements and capabilities.

So many things can feel off with it. To start with, it could come with a clunky editor that doesn’t inspire your resources to do their best writing. Or, it could have restrictive pricing schemes where it just won’t be feasible to get your entire team to contribute. It could also come shipped with a poor search functionality that will fail to help you find what you need among other unrefined features!

Choosing a technical documentation software is indeed a lot of work. But we’ve done the homework for you. Before we see our picks for the best technical documentation software, though, let’s look at what technical documentation is.

So what is technical documentation?

Technical documentation can mean different things in different contexts. 

In one context, technical documentation for a business might be just documenting the content that its engineers or developers or technical resources use — source code, for example.

But it goes beyond that. Here’s one great way of looking at it (via Transcom):

The term ‘technical documentation’ refers to different documents with product-related data and information that are used and stored for different purposes. “Different purposes” mean: Product definition and specification, design, manufacturing, quality assurance, product liability, product presentation; description of features, functions and interfaces; intended, safe and correct use; service and repair of a technical product as well as its safe disposal.


So you can see that the term technical documentation has evolved to include every piece of documentation a product uses across its lifecycle.

Following this definition, everything right from how-to guides, SOPs, product documents to release notes are all examples of it. That means your technical documentation software solution must support all of these.

Choosing a technical documentation software Solution

In addition to reviewing a solution for its support for the different documentation types, pay attention to these selection criteria. 

  • Pricing plans: Technical documentation software solutions often come with per user per month billing plans that are capped at storage limits and page views. These quickly become a problem when you have a large support team and get a high volume of hits, these can add up fast.
  • Good access control: Your technical documentation is usually a mix of private and public pieces. So your technical documentation software should come with at least some level of access control.
  • Comfortable writing and editing experience: Of course, you need a good writing and editing experience that your technical writers and other team members enjoy.

So with all that in mind, let’s drive straight into our list of the top technical documentation software solutions you could choose from.

What are software documentation tools?

Software documentation tools are applications that provide content creation, collaboration, and organization capabilities for software developers to maintain software and write programs. Documentation includes lists of instructions with helpful tools, such as videos and links, so developers can quickly access and update processes. Many documentation tools aren’t just for developers, either: technical writers and other employees within an organization also use them to document company processes that don’t involve software development or engineering. 

The main benefits of documentation tools are: 

  • Organization of a wide range of company processes and tasks, including software installation and development
  • Centralized content management, so that new documents can be published and updated in one place
  • User-based access permissions and customizable notifications


Software documentation has been in the periphery of software industry concerns for a long time. In fact, the first book on software documentation was published over half a century ago. The software industry is independent and rapidly growing, so it’s logical to think that the software documentation needs are going to grow as well. If you’re a programmer, or interested in how to write documentation, you will find quite a few useful links on this page.

Software documentation is a developer’s best friend. Unfortunately, creating high-quality documentation can be tedious and time-consuming. This can cause many developers to put off this important task. A number of developers share their documents using standalone documentation tools like MS Word, Google Docs and more.
