What is 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.
