Scalar

Scalar is a platform for building API documentation that looks professional and works smoothly. You provide your OpenAPI document, and Scalar transforms it into easy-to-read pages with examples and testing tools built in.

The platform offers several products working together. The API Reference shows your documentation in a clean layout. The API Client lets developers test endpoints directly. The platform also includes tools for managing multiple versions of your API documents and syncing with GitHub.

Scalar is completely open-source, which means the code is public and free to use. You can host it yourself or use their cloud service. The free plan covers basic features, while paid plans add collaboration tools, custom domains, and better support.

Readme

Readme is a platform that lets you create and publish interactive developer documentation for your APIs. Unlike traditional documentation tools, Readme automatically generates API references from your OpenAPI or Swagger files and keeps everything in sync with your code.

The platform includes a built-in editor where you can write guides, add code examples, and explain how your API works. Developers using your API can test endpoints directly from the documentation with the Try It feature, making it easier to understand how everything works.

Readme also provides analytics so you can see which parts of your documentation get the most views and where developers might be getting stuck, helping you improve your API experience over time.
