Why teams are choosing GitBook

API code samples

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

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.

API endpoints

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.

Git Sync

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.

Workflow

Protect your primary docs

GitBook uses a Git-like branching workflow for your documentation. That’s great for open-source docs because it stops changes going live accidentally, while encouraging everyone to make edits and give feedback. The result? Better quality docs with fewer conflicts.

Authentication

Control access for authorized users

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.

“The GitBook design looks good out of the box, with many options to customize it further. A consistent experience across the product is key, and we enjoyed being able to make our docs on-brand.”
