GitBook

Modern documentation platform that syncs code with content for engineering and product teams.

GitBook centralizes technical knowledge by integrating directly with GitHub and GitLab workflows. It supports Markdown and WYSIWYG editing to bridge the gap between developers and non-technical stakeholders. Teams like Adobe and Sentry use it to manage internal wikis and public API docs (including versioning and custom domains). The platform automates documentation updates through Git Sync: ensuring docs stay current with every code commit.
