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
