Litestar has first class OpenAPI support offering the following features:

  • Automatic OpenAPI 3.1.0 Schema generation, which is available as both YAML and JSON.

  • Builtin support for static documentation site generation using several different libraries.

  • Simple configuration using pydantic based classes.

Litestar includes a complete implementation of the latest version of the OpenAPI specification using Python dataclasses. This implementation is used as a basis for generating OpenAPI specs, supporting builtins including dataclasses and TypedDict, as well as Pydantic models and any 3rd party entities for which a plugin is implemented.

This is also highly configurable - and users can customize the OpenAPI spec in a variety of ways - ranging from passing configuration globally, to settings specific kwargs on route handler decorators.
