## What it is
A Python CLI tool that generates a FastAPI application, including Pydantic models and routers, from an OpenAPI document. It builds on datamodel-code-generator for the model layer and supports custom templates and visitors.

## Use cases
- generate a fastapi app from an openapi spec
- scaffold fastapi routes from swagger yaml
- convert openapi file to pydantic v2 models
- generate api server code from openapi 3 document
- bootstrap fastapi project from existing api contract
- create typed fastapi models from  schema

## When to choose
- you have an OpenAPI/Swagger spec and want a working FastAPI skeleton
- you want Pydantic models generated automatically from the spec
- you need customizable code generation via templates or custom visitors

## When to avoid
- you're building a FastAPI app from scratch without an OpenAPI spec
- you need a generic OpenAPI client generator rather than a server app
- you use a framework other than FastAPI
