What are Scalar and API Hub?
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.
API Hub is an all-in-one platform for the complete API development process. It lets you design APIs using a visual editor or code, test them automatically, create documentation, and share with users through branded portals.
The platform works with OpenAPI and AsyncAPI standards, supporting both traditional REST APIs and event-driven architectures. It includes tools for checking that your APIs follow your team's rules, generating mock servers for testing, and validating contracts between services.
Teams can work together with version control, commenting features, and role-based permissions. The platform connects with popular development tools like GitHub, CI/CD pipelines, and API management systems. Whether you need basic API design or complex enterprise workflows, API Hub provides the features you need.
