GitBook is an API & developer docs tool for Developers and Small businesses, offered as freemium ($65/mo). Based in France, founded in 2014. Popular alternatives include Postman, Apidog, Bump.sh.
About GitBook
GitBook is a documentation platform used for product docs, API references and internal knowledge bases. It started as an open-source command-line tool for writing books in Markdown and evolved into a hosted SaaS with a block-based editor, so non-technical writers and engineers can work on the same content without friction.
The main draw is two-way Git sync with GitHub or GitLab: content can be edited in GitBook or as Markdown files in a repository, and changes flow both ways. Change requests work like pull requests for docs, with review and merge. OpenAPI blocks render interactive API references, and GitBook AI answers reader questions from the docs and helps authors write. Pricing moved to per-site tiers in 2024: a free plan for individuals publishing public docs, Essential for custom domains, AI and analytics, and Ultimate for authenticated access, variants and SSO.
GitBook fits product and developer teams that want Git-backed docs with an editor that product managers and support staff can also use. Costs rise when you publish several separate sites, design customisation is limited compared with code-based tools, and authenticated docs require the top tier. Mintlify is more polished for developer and API docs, Docusaurus is free if you have engineering time, and Notion or Confluence are simpler for purely internal wikis.
