## What it is
Litestar is a production-ready, highly performant, extensible ASGI API framework for Python, formerly known as Starlite. It provides REST API building with OpenAPI generation, dependency injection, and support for Pydantic and msgspec serialization.

## Use cases
- build rest apis in python
- async asgi web framework
- generate openapi docs automatically
- high performance python api server
- build scalable backend services
- replace flask or fastapi with a faster framework

## When to choose
- you need a high-performance async Python API framework
- you want built-in OpenAPI/Swagger documentation
- you need dependency injection and layered architecture out of the box
- you want flexibility between Pydantic and msgspec for validation

## When to avoid
- you need a minimal WSGI framework like Flask for simple sync apps
- your team relies on a framework with a much larger plugin ecosystem
- you need Django's full-stack features like ORM admin and templating
