GitBook vs Swagger UI
Instant API code samples in the right language
API documentation in GitBook gives your users a ton of information at a glance. And because it automatically generates code samples for API endpoints, it’s easy for everyone to find and use the information and code they need.
Customize and add context to your API docs
Customize your docs to match your brand, then organize them however you want. Group related operations together, or split them into different pages. Add an introduction, interactive guides, and any other content that will help your users. You’re in control.
Test your APIs right in GitBook
Let users and developers try API endpoints right on the page with our OpenAPI blocks powered by Scalar. Simply click Test It to open up an API client where you can add headers, variables and more — then run a live test.
Update your API docs from GitHub or GitLab
With our Git Sync integrations, you can set up a two-way sync with your codebase. Now, when you make changes to your API, you can update your API docs at the same time — right in GitHub or GitLab.
Publish access-protected API docs for key customers or use cases. Then secure them using your own authentication platform or one of our built-in integrations — so you choose precisely who can access your APIs.
