7 Best Free Knowledge Base Software in 2025

Not very long ago, every time we needed an answer to a question, we’d spend hours leafing through pages of books — hoping we stubble upon a tidbit that would help. While it wasn’t the most convenient way to look for information, it was our only choice.

What’s even better? Many knowledge base software are available for free, making information sharing and problem-solving more efficient than ever.

What Is a Knowledge Base?

A knowledge base is like a digital “help yourself” hub, where employees and customers can instantly find answers without needing to ask someone. Think of it as a one-stop shop for tips, best practices, and workarounds. 

For your employees, an internal knowledge base is their go-to library for their queries —- be it technical or something related to company policies. Instead of asking a colleague, they just search and get their answer; so much more efficient!

For customers, it’s a self-service guide on your products or services. So, if a customer has a hiccup with a new purchase, they can just go to your knowledge base, search for a solution, and find expert advice without needing to call in. 

It’s all about efficiency and giving your customers the choice to solve their problems whenever and wherever.
