Best Knowledge Base Software in 2026

Knowledge base software helps teams publish and maintain information for people who need it. Compared on article limits, publishing audience, and content analytics, the entries also vary in version history and SSO support. Custom domain availability may matter for published material, while free plans and paid-from pricing give you cost details to compare. Nuclino, ProProfs Knowledge Base, and Confluence are among the options. Think about who needs to access your content, how your team will keep it up to date, and which listed controls or insights are important for making that information useful.
