# GitBook

Canonical: https://inetgeek.com/docs-platforms/gitbook/

Hosted documentation platform with a web editor, Git sync, OpenAPI-based API reference and AI features, priced per published site.

## Who it suits

A team that wants a collaborative editor with two-way Git sync and an OpenAPI reference, priced per published site: Essential is $65 per site per month billed annually plus $12 per additional user, and the free plan covers one user.

Consider something else if You publish several docs sites or have many editors, since the bill grows with both. AI answers start at Essential, SAML SSO is Enterprise-only, and SDK generation is limited to code examples.

## iScore

84 / 100 (80% interval 75–92), rank 3 of 10 in docs-platforms — interval overlaps the next rank, so this is an ordering, not a finding.

inetGeek's own reading, computed from sourced facts against category peers by disclosed rules. Not a provider claim. Intervals are 80%; a provider with few documented facts is pulled toward the category middle rather than scored on what little is known.
Read this score with care:
- Documented but not scored, because the page states it as text with no comparable number or a yes/limited/no (a one-time, usage-based or other-vendor price, or a per-site choice): minimum_paid_price. Read them on the provider page; the score neither rewards nor penalises what it could not compare.
