The hyperglass API is based on the powerful [FastAPI](https://fastapi.tiangolo.com/) framework, which includes automatic API documentation using the [OpenAPI](https://www.openapis.org/) specification. If you plan to provide your users with API access to your hyperglass instance, it is highly recommended to leave this enabled.

FastAPI provides built in support for both [Swagger UI](https://swagger.io/tools/swagger-ui/) and [Redoc](https://redocly.github.io/redoc/), which are open source projects that create a pretty web UI from an OpenAPI specification.

:::note From the developer
I'm partial to Redoc, partially because I find it to be more aesthetically pleasing, and partially because it's written in [ReactJS](https://reactjs.org/), just like the hyperglass UI. At some point, I plan to migrate away from the built-in Redoc page and integrate Redoc directly with hyperglass.
