Open Source Knowledge Base Software List for 2024

There’s no denying that a knowledge base can make a major impact on your organization. 

Whether it's to help provide better support to your customers or to enable your employees to find the information they need to do their job, a finely-tuned knowledge base can make all the difference when it comes to how knowledge and information flows through your business.

And with plenty of options on the market out there, there’s certainly no shortage of open source knowledge base software.

But how can you tell you’re not investing time into installing and learning new software that your team won't use anyway? How can you avoid the time and effort put into an open source option that you later determine to not be a good fit for your needs? 

It’s simple—do a little research beforehand.

We know, we know—you don’t have endless time to invest in that kind of thing (what with a business to run and all). That’s why we’ve created a helpful list of the must-consider open source knowledge base software that companies of all niches, industries, and sizes should consider. 

We’re even throwing in a little helpful knowledge that should equip you with the information needed to choose the right software for you—like what knowledge base software is in the first place, the benefits of open source software, and how to address your unique needs as a company to choose the right software for you.

What is an Open Source Knowledge Base?

Before we dive into which open-source knowledge base software you should consider for your business, we should probably ensure we’re on the same page about what exactly open-source knowledge base software is. 

First things first, let’s start with the term knowledge base.

A knowledge base is a central place that allows structured storage of information where users can search for and access this information.  Knowledge base software should be the key tool that helps make this process seamless, simplified, and efficient.

Knowledge base software is designed to help you create and manage your knowledge base to the best of your ability. this usually includes setting up the knowledge base architecture, creating and editing documentation, searching, and analyzing your knowledge base, and more.

Ideally, this is the irreplaceable piece of the puzzle that operates your entire knowledge management system that helps orchestrate, manage, and optimize the flow of knowledge within your organization. 

That part seems pretty clear, right?

Next, we’ll move on to the term open source—this simply refers to original source code that is freely and readily available and modifiable as developers and business owners see fit. 

Typically, when businesses want to create a knowledge management portal that allows customers to troubleshoot their issues, they look to create a knowledge base and open source solutions can be a potential solution due to pricing (typically free) and ability to customize.

As promised, we’ve listed out the best open-source knowledge base software options below. Read up on the highlights, the benefits, and the need-to-know details of each to see which software might be the best open source choice for you and your business.

Open Source Knowledge Base Benefits

Often when considering the open source route, the argument for SaaS knowledge base software comes into play—and truthfully, it all comes down to preference, pain points, and the unique goals of a company. While we can’t say that SaaS doesn’t offer extensive benefits to companies, we can say that open-source knowledge base software does have its own set of strengths.  with open source means that you're going to build your custom knowledge base in-house or employ a developer to build it for you.

Here are a few of the benefits you simply can’t ignore when it comes to open-source knowledge base software.

Benefit #1: It's Usually FREE

This is arguably the most notable benefit of open source software—especially when compared to pricier SaaS choices. Whether your budget for creating a knowledge base is minimal due to business-related choices or you’re simply a start-up looking to keep costs down but information organization up, there’s no denying that a free solution that helps manage your organization's knowledge is a big win. 

Benefit #2: The Ability to Self-Host

If you’d rather know and understand where your own knowledge base system is being hosted (and if you really only trust your own servers), then open space systems are probably the right choice for you.

Most open source setups allow you to host your software on your own server as opposed to SaaS options which are hosted by the software provider.

Benefit #3: The Ability to Integrate With Your Existing System 

Just by its nature, open source is pretty easily adaptable, making it an obvious choice for those who want to integrate new software with their current system.

If you’re building your own knowledge base on open source code, it’s highly unlikely it won’t work with your current setup—though, admittedly, this is a benefit that’s mostly available to those building their entire systems from scratch. 

Still, even if you’re integrating open-source knowledge base software into existing SaaS, there are ways to incorporate APIs to make sure everything works together. 

Benefit #4: You’re Building it, You’re in Control 

While other types of knowledge base software offer the ease and convenience of having everything pretty plug and play, open source grants you the opportunity to create a completely customizable platform that does everything you want it to and nothing you don’t. 

In other words, you’ve got the power and control that goes hand in hand with creating a tailor-made knowledge base software. 

This means there’s no learning to live without features that SaaS vendors might get rid of, no annoying functionalities you don’t need, and no changes that happen without your approval. 

Why SaaS Knowledge Base Software Might Be a Better Option

We won’t deny that open-source knowledge base software has its benefits (in fact, we wrote the entire section above with that exact point in mind).

But the truth can’t be avoided. 

Sometimes, SaaS knowledge base software is the better choice for a specific company because it can offer features, capabilities, and functionalities that might not be included in an open source knowledge base tool.

The Many Benefits of SaaS Knowledge Base Software 

  • Simplicity and streamlined use to ensure a seamless experience 
  • Customer support for when things get sticky or tricky 
  • Customizable plans that meet your needs—without all the work of building it yourself 
  • Low-cost ownership that could end up being more affordable than “free” software once you consider the time and effort that goes into building that knowledge base software (and potential licensing costs)
  • Continuously improved by the vendor to ensure you have cutting-edge technology 
  • Made by experts that know what they’re doing 
  • Reliable with plug-and-play capabilities 
  • Easy to learn and easier to use 

Ultimately, the right knowledge base software is different for every company, their current needs, their future goals, and their knowledge sharing and accessing pain points. What might work best for one business could be the wrong choice entirely for another. 

It’s a unique choice that should be made based on your company’s own needs and goals.
