We detect the most documentation & knowledge base sites in United States, United Kingdom, Canada, Australia, Germany. Country here is the company's registered location in our enriched data rather than where the site is served from, so read it as a ranking of markets rather than a measure of any single one.

How do I choose the right documentation & knowledge base platform?

Start from your own size, industry and primary use case rather than from share. Zendesk, Foxit and MediaWiki are the three we detect most often in this category, which tells you what is common, not what fits you. Compare their integrations, pricing tiers and support commitments against the workflow you actually run, and check each vendor's own documentation for current capabilities.
