Knowledge Base

Self-hosted wiki and documentation platforms. Organize team knowledge, SOPs, and documentation without per-user SaaS costs.

Published: March 1, 2026

Why Self-Host Your Knowledge Base?

Documentation is a long-term asset. Locking it in a SaaS platform means ongoing per-user costs and vendor dependency. Self-hosted wikis give you:

  • No per-user fees — Add your entire team without escalating costs
  • Data sovereignty — Sensitive SOPs and internal docs stay on your servers
  • Longevity — Your documentation survives regardless of SaaS pricing changes or shutdowns
  • Customization — Custom branding, SSO integration, and workflow automation

When to Choose Self-Hosted

Self-hosted knowledge bases work best if you:

  • Have 10+ users (per-user pricing compounds quickly)
  • Store sensitive internal documentation
  • Want a simple, maintainable system without the Confluence learning curve
  • Need LDAP/SSO integration with your existing authentication
  • Prefer to own your data long-term
