everything you need to build modern apis litestar provides all the tools you need out of the box with minimal configuration required data validation and parsing leverage the power of type hints to define how data should be validated parsed and serialized open ecosystem define schemas and models for validation with standard types such as dataclasses libraries like pydantic msgspec attr or integrate your own openapi automatically generated openapi schemas help to document apis and integrate with the frontend via typescript schema generation interactive api documentation interactively explore your apis through swagger redoc or stoplight elements powered by openapi middlewares handle rate limiting cors csrf compression logging and many more common tasks with litestar s built in middlewares data stores interfaces for various key value stores that seamlessly integrate with your application and third party extensions orm integration first class sqlalchemy support let s you use your models for validation and serialization directly reducing code duplication dependency injection powerful dependency injection on all application layers aides in code decoupling and reduces
