Ariadne vs Strawberry GraphQL

Ariadne is an open-source Python library for building GraphQL APIs with a schema-first design. Developers describe an API using GraphQL Schema Definition Language and connect schema fields to application logic with resolver functions. The server supports asynchronous and synchronous query execution and can be served through WSGI or ASGI apps. The project describes interoperability with web frameworks and includes a Django integration example. Ariadne Codegen creates a typed Python client and Pydantic models from a GraphQL schema and operations; generated client results are validated against those models at runtime. An optional SQLAlchemy 2.0 integration supports synchronous sessions in WSGI and ASGI, while AsyncSession is limited to ASGI and has a documented limitation involving sibling root fields. Ariadne implements the GraphQL multipart request specification for uploads. Its default Upload scalar is write-only and supports values passed through variables. Security documentation discusses denial-of-service and credential-leakage risks and gives mitigation guidance. Ariadne is self-hosted and free, and the site lists Linux, web, and API platforms.

Strawberry GraphQL is a free, open-source Python library for creating GraphQL APIs. It uses Python type hints to define schemas and support a developer-oriented workflow. Async/await allows resolvers to run without blocking, while schema and field extensions provide places for custom logic. Generics support reusable types, and federated GraphQL schemas are supported. Built-in dataloaders can batch multiple queries into one. Documentation lists integrations for Django, Channels, FastAPI, Flask, Quart, Sanic, Chalice, Starlette, Litestar and AIOHTTP, while noting that the integration table may not be current. Installation uses pip and requires Python 3.10 or later. Strawberry is MIT licensed and intended for self-hosted deployment. Authentication is handled by the web framework; authorization uses Permissions classes. API explorer, client code generation and operation testing are listed. Enterprise support is available through Farbun.
