The Top 25 Knowledge Base Software Solutions for 2024

At KnowledgeOwl, we know that picking the right knowledge base tool in a sea of options and review sites is rough.

Your knowledge base is like a virtual nest where you gather and store all of your collective product wisdom. If that’s true, your knowledge base software is the tree to your nest. It provides the structure, the organization, and the means to keep your content useful, navigable, and up to date for your audience.

At the risk of stating the obvious, it’s really important to find the best solution for your team and your customers.

But maybe you're a barn owl, and a hay loft is the perfect place for you. Or you're a city owl, and you prefer a skyscraper windowsill for your nest. Just like with owls, your company has unique needs and requirements, which means that not just any knowledge base tool will do.

We've created this guide to make finding that perfect solution for you just a little bit easier.

It will help you scope out what you need from your help center software, while also giving you the basics on some of the best tools out there today—a jump start on comparing knowledge base solutions without having to hit up all the review sites (unless you really want to!).

Figuring out what you need from your knowledge base software

There are so many options out there for knowledge base software, and trying to wade through them without a clear purpose and audience is like throwing a dart at a dartboard with a blindfold on—you'll still probably hit something, but probably not the bullseye.

There are three questions we recommend asking yourself before you start scouting knowledge base tools:

  1. Who will be your authors?

  2. Who is your audience?

  3. What features are most important?

Who will be your authors?

Will you have a dedicated team of knowledge creators writing and managing your help center content? Will you have a single person writing most of your content? Or will your knowledge base be built by a team of folks in their spare time (for instance, by a support team who is adding knowledge when they're not in the queue)?

The answer to this question will greatly influence the solution you choose, because some tools specialize in wiki-style knowledge bases which are created and curated collaboratively (think Guru or Notion), whereas others focus on being used as a single source of truth (such as KnowledgeOwl or Document360).

Who is your audience?

Are your primary users employees of your company, or are they customers seeking help with your product? Are they technical users, like software developers? 

Understanding the audience for your knowledge base is key, because while some tools offer solutions for both internal and external knowledge-sharing (like KnowledgeOwl), many cater to one or the other. And if you're working with a technical audience, you'll want to pick a public solution that can handle specialized content like code and API documentation.

If you're struggling with this step, check out our guide on defining the purpose of your help center. It'll walk you through some helpful questions for figuring out what you want your knowledge base to achieve, which is closely tied in with who you want it to help.

What features are most important?

Once you understand who will be creating content and who will be consuming it, you'll have a better idea of what features you'll need in your knowledge base software.

But if you've gotten to this point and you're still not sure, don't worry! Unlike with the first two questions, your approach to this question can be more relaxed and exploratory. 

You may even want to look at a few KB software options in the audience category you need to get an idea of their features, making lists of the features that are must-haves for your team, the ones that are nice-to-haves, and which features, if any, are must-not-haves.

We also have a great resource that can help you accelerate this step. Our guide to common knowledge base software features divides features up into five easy-to-digest categories: navigation, content, integrations, metadata, and permissions.

Researching and comparing knowledge base solutions

Before we dive into the good stuff—the KB software!—let's talk about how our list is organized and how you can use it to compare your top picks.

We've divided these help center solutions by the main audience each serves: both internal and public audiences, for internal audiences, or for public audiences. Under each solution, we'll tell you what type of software it is (for instance, if it's standalone KB software, wiki software, etc.), what the best use case is for the software, and quotes from real customers if they're available.

As you work through these knowledge base software options, you can use our Tool Comparison Rubric to note your favorites (we recommend no more than five), whether they include your desired features, your score for how the solution handles each feature, and any notes you have. 

We've pre-populated the spreadsheet with some of the most common requirements we've seen organizations look for, but edit those to match your requirements. We haven't weighted the feature scores, but you may want to do so if there are certain features that are more important to you than others.

Once you've settled on your favorites, we recommend getting demos or creating trial accounts so that you can see the software in action and whether the features are implemented in a way that makes sense for your team.

Lastly, if you're needing to make a case for implementing your knowledge base software of choice, we've created a Knowledge Base Brief template to help you do just that. 

Now, without further adieu: let's get to the software!
