GitBook

GitBook is a cloud-based tool designed specifically for creating documentation. Think of it as a specialized writing platform where you can build everything from simple user guides to complex API documentation. The platform uses a block-based editor, similar to modern website builders, making it easy to add text, images, code examples, and other content without coding knowledge.

What sets GitBook apart is its two-way sync with GitHub and GitLab. This means developers can write documentation directly in their code editor, while content teams work in GitBook's visual interface. Everything stays synchronized automatically. The platform also includes AI features that help users find information quickly and assist in creating content. You can publish documentation publicly or keep it private with password protection.

Redocly

Redocly is an API documentation platform that helps you build professional developer portals. You start with an OpenAPI file that describes your API, and Redocly transforms it into clean, readable documentation with examples and interactive features.

The platform includes several products working together. Reunite is where teams write and review content. Realm delivers the final documentation to your users. Redoc is the open-source engine that renders API reference docs. Reef helps you organize and discover all your APIs in one catalog.

Unlike basic documentation generators, Redocly gives you a complete developer portal. You can add guides, tutorials, and custom pages alongside your API reference. Everything is version controlled and updates automatically when you change your API definition.
