Litestar

A high-performance, production-ready Python framework for building powerful APIs with strict type safety.

Litestar (formerly Starlite) delivers a lightweight yet feature-complete toolkit for modern Python development. It leverages Pydantic and Python type hints to automate validation, serialization, and OpenAPI 3.1 schema generation. The framework outperforms FastAPI in many benchmarks while providing built-in support for dependency injection, enterprise-grade middleware, and asynchronous data handling. By integrating advanced features like DTOs (Data Transfer Objects) and sophisticated plugin systems, Litestar eliminates the need for dozens of third-party dependencies in complex backend architectures.
