It lets you declare request and response schemas using either marshmallow or Pydantic, then automatically validates incoming JSON, deserializes it into your schema, and serializes responses back out\u2014all while generating an OpenAPI specification and interactive Swagger UI documentation on the fly. You write decorators like `@app.input()` and `@app.output()` on your route functions, and APIFlask handles the plumbing: validation errors return JSON, successful responses are formatted consistently, and your API docs stay in sync with your code.\n\nIt's built on top of Flask's ecosystem (using flask-marshmallow, webargs, apispec, and flask-httpauth) and remains fully compatible with Flask extensions and patterns. The framework is ORM/ODM-agnostic, so you can use it with SQLAlchemy, MongoDB, or any data layer. It supports both synchronous and asynchronous route handlers, and you can choose between multiple documentation UIs (Swagger UI, Redoc, Elements, RapiDoc, RapiPDF).","worth_installing":"Yes. APIFlask is actively maintained, has no known vulnerabilities, installs with low friction, and solves a real problem\u2014reducing boilerplate in Flask API development while keeping you in the Flask ecosystem. It's suitable for production use (Development Status: Production/Stable) and works with modern Python versions. Choose it if you want Flask's flexibility with structured API patterns and auto-generated docs, without adopting a heavier framework."},"id":"apiflask","links":{"html":"https://skillfed.io/packages/apiflask","md":"https://skillfed.io/packages/apiflask.md","pypi":"https://pypi.org/project/apiflask/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-23","license_spdx":null,"license_treatment":"permissive","name":"APIFlask","python_support":"unspecified","summary":"A lightweight web API framework based on Flask."},"popularity":{"monthly_downloads":211229,"position":9482,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.1.1"}
