What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

A pluggable Python library that generates OpenAPI (Swagger) specifications, supporting OpenAPI versions 2 and 3. It is framework-agnostic with built-in marshmallow schema support and utilities for parsing docstrings.

Use cases

  • generate an OpenAPI spec from a Flask app
  • document REST APIs with OpenAPI 3
  • generate swagger documentation from marshmallow schemas
  • extract API specs from docstrings
  • build OpenAPI definitions for a Python web framework

When to choose

  • you use marshmallow schemas and want OpenAPI docs generated from them
  • you need a framework-agnostic OpenAPI spec generator in Python
  • you want to document Flask or similar REST APIs

When to avoid

  • you need a full interactive documentation UI rather than spec generation
  • your API is not Python-based
  • you want automatic spec generation without any schema or docstring annotations
