Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Noticeably faster and simpler than heavier tools like Notion or Confluence
Free plan is generous enough for small teams to fully evaluate before paying
Unique graph view makes it easy to see how documentation is interconnected
Bootstrapped, profitable company with a stable, long-running product (founded 2015)
Real-time multiplayer editing works smoothly even with several simultaneous editors
Cons
Fewer advanced features (databases, automations, integrations) compared to Notion or Coda
Free plan's 50-item cap is restrictive for growing teams
AI features and audit logs are locked behind the Business tier
Smaller company size than VC-backed competitors means a slower pace of major feature releases
Less extensive third-party integration ecosystem than larger knowledge-base platforms
GitBook
Pros
Combines Git-based version control with an easy-to-use visual editor for both technical and non-technical writers
Strong built-in API reference and playground tooling for developer documentation
Increasingly capable AI search, writing, and question-answering features grounded in a team's own docs
Polished, professional out-of-the-box design for published documentation sites
Generous free tier for a single basic site
Cons
Per-site pricing can get expensive quickly for organizations needing multiple documentation sites
Additional per-user charges stack on top of the base site price at every paid tier
Advanced AI features are reserved for the pricier Ultimate and Enterprise tiers
Free tier excludes custom domains and real-time collaboration, limiting its use for public-facing docs
Smaller ecosystem/plugin community compared to open-source alternatives like Docusaurus
