Scalar In This Page
Scalar is an open source API platform with OpenAPI and Swagger support.
This page uses Scalar as an API reference renderer for OpenAPI files. It is useful when you want a modern reference layout with request examples, navigation, schemas, and API client style workflows.
The Scalar viewer runs in your browser. Loading external OpenAPI URLs and making browser requests can be limited by CORS, so open a downloaded file from disk if a public URL is blocked.
Compare this with the Online Swagger UI, OpenAPI Explorer, Stoplight Elements, Zudoku, and Redoc pages.
