4 Best Free Knowledge Base Software

By | 8 min read | Published

Knowledge base software helps create and manage self-service content.

Are you an online retailer or a startup owner struggling to answer the many queries customers have about your product or service? Do you wish to provide information to prospects but without answering multiple phone calls? If your answer is yes, you might want to try knowledge base software.

A knowledge base platform allows you to create, organize, and manage self-service content for customers. It helps enhance the customer experience, as clients don’t have to rely on the support team to get the information they want. You can also use the software to set up an internal knowledge base for employees.

Despite the benefits, purchasing a knowledge base system is a significant investment. Before investing, why not consider free software to get an idea of how well it works for your business?

This article highlights the four best free knowledge base software options (listed alphabetically) based on user reviews and ratings. (Read how we selected these products.)

How to choose the right free knowledge base software

Selecting a free knowledge management solution isn’t always easy, especially with so many available options on the market. Here are a few considerations to make when shortlisting a free knowledge base system for your business:

  • Select a tool that allows you to organize content. If you need to store multiple articles in one knowledge database, then opt for a knowledge base tool that allows you to not only create self-service articles but also segregate them into categories (based on topics, issues, themes, etc.) and then move them into customizable folders. This will help visitors browse through your content library and find relevant articles with ease.
  • Select a tool with a powerful search engine. Users search articles or support content to find a quick solution to their issues. A powerful search engine, therefore, is a must-have feature in your knowledge base solution. Check if the free product you’ve shortlisted can scroll through thousands of articles in your knowledge base and deliver relevant results based on the keyword used in the search query. The software should also provide for partial search, allowing users to correct misspelled words and typing errors in their search queries. In addition, customers should be able to easily locate the search bar, enter their queries, and find relevant solutions within the first few results.
  • Select a tool that offers mobile optimization: Make sure the knowledge base platform you select works equally well on all devices, including smartphones. This will provide your clients the best customer experience and instant solutions, irrespective of the device they use. Select a software platform that allows you to manage knowledge base articles even on mobile devices. In addition, the software should offer customizable mobile-ready themes with easy adjustments for size and layout to ensure your knowledge base looks aligned and works well even on mobile browsers.

Common questions to ask when choosing free knowledge base software

Here are some common questions to ask software providers before finalizing your purchase:

Does your software offer reporting capabilities?

Before you finalize any knowledge management software, ask the vendor about the product’s reporting capabilities. Look for a tool that offers usage and content reporting, such as the number of views on your articles and the time viewers spend on them. These metrics help identify gaps in the knowledge base content and plan improvements.

Does your software allow customization?

Your shortlisted free software should allow you to customize certain aspects of your knowledge base, such as the site layout, content format, font size, URL, themes, logos, and dashboard. Before selecting a knowledge base tool, make sure to ask the vendor about its customization capabilities.

Does your software support file attachments?

At times, you’ll need to add elements such as images and videos to your knowledge base articles to make them engaging and informative for readers. Ask the vendor whether their knowledge management software allows you to embed templates, PDF files, images, audio clips, and video clips into the articles.

How did we choose these products? We didn’t—you did

To find your ideal software match, you need information you can trust so you can save time, stay on budget, and focus more energy on growing your business. It’s why we vet and verify all our user reviews and recommend only the tools endorsed by people like you.

In other words, our product recommendations are never bought or sold, or based on the opinion of a single individual—they’re chosen by your peers, reflecting the views and experiences of our independent base of software reviewers.


​​At Capterra, we objectively select and rank products based on a methodology developed by our research team. Some vendors pay us when they receive web traffic, but this has no influence on our methodology.

To be considered for this list, products have to:

  1. Have at least 20 unique product reviews published on Capterra within the past two years, with an average rating of 3.0 or higher (as of April 19, 2022). We selected 4 products with the highest ratings to feature in this article.
  2. Offer a free, stand-alone version of the software—not a trial version you have to purchase after a certain amount of time to get the full experience.
  3. Meet our definition of knowledge base software: “Knowledge base software is a self-serve online library that enables businesses to provide both customers and teams detailed information about their products, services, topics, or departments.”

The “Best functionality” tool is identified based on the highest user ratings for functionality that a vendor received based on publicly available reviews as of April 19, 2022.

The “Most affordable” tool is identified based on the lowest pricing a vendor offered on their website in terms of cost to upgrade as of April 19, 2022.
