Astro Starlight

Astro Starlight is a documentation theme built on the Astro web framework. It provides a ready-made structure for creating documentation websites that are fast, accessible, and easy to maintain. Unlike other documentation tools, Starlight ships minimal JavaScript to the browser, resulting in faster load times and better performance.

The tool supports writing content in Markdown, MDX, and Markdoc formats, giving you flexibility in how you create your documentation. It includes automatic navigation generation, built-in search powered by Pagefind, and responsive design that works on all devices. Starlight also supports multiple languages out of the box, making it suitable for global documentation projects. The theme is highly customizable through configuration files, allowing you to match your brand while keeping the simplicity of setup.

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.
