Choosing well
Can I use it on an Android phone or tablet?
Check whether the product offers an Android app if you need to read or manage knowledge content on a Xiaomi, Redmi or POCO device. Platform information covers web, API, self-hosted, Windows, Linux and macOS, without specifying Android availability.
How will I publish articles for readers?
Look at the intended publishing audience and article limit to judge whether a tool suits your plans for sharing information.
Check custom domain support if you want articles under a domain associated with your organization.
Does it support SSO and version history?
Review SSO support for your sign-in requirements; version history can help when you need to inspect or restore older content.
These are separate comparison points, so verify both rather than assuming one implies the other.
Can I start with a free plan or trial?
Check whether a product offers an ongoing free plan and what its paid entry price is. A trial is a separate option that may help you assess a paid product before committing.
ProProfs Knowledge Base lists a free plan, a 15-day trial, and paid plans starting at $0.99 per user per month with annual billing.
Do I need web, self-hosted, or desktop access?
Choose based on how your team needs to access and run the software. Listed options span web, self-hosted, Windows, Linux and macOS, with API access also included.
If open-source licensing matters, check the licence for the specific product rather than relying on its deployment options.
Questions people ask
What should I compare when choosing knowledge base software?
Review free-plan availability and the paid starting price, along with publishing audience, article limit, custom domain, SSO, version history and content analytics. Check Android availability separately if you will use a Xiaomi, Redmi or POCO device.
Can I use knowledge base software on Android?
The platform details provided here do not specify Android app availability. Check the product's current app support; web access is listed as a platform for some products.
Is a free knowledge base plan available?
The list includes products with free plans and products with free trials. Check a specific product's plan details, since a trial is not the same as an ongoing free plan.

Self-hosted appears among the platform options compared here. Check individual product details to confirm whether a tool fits your deployment needs.
What does content analytics tell me in a knowledge base?
Content analytics is a comparison point for this list. Check the individual product's feature details to see what analytics it offers.
