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.

Apidog

Apidog is a platform that handles the complete process of creating and managing APIs. You can design your API structure, test how it works, create clear documentation, and share it with your team, all from one application.

The platform follows a design-first approach, which means you plan your API before writing code. This helps catch problems early and keeps everyone on the same page. It automatically creates mock servers so front-end developers can start working before the back-end is ready.

There is a free version that works great for small teams and individual developers. Paid plans add more features like unlimited projects, advanced testing tools, and priority support for growing businesses.
