Ariadne

Ariadne is a Python library for implementing GraphQL servers.

It presents a simple, easy-to-learn and extend API inspired by Apollo Server, with a declaratory approach to type definition that uses a standard Schema Definition Language shared between GraphQL tools, production-ready WSGI middleware, simple dev server for local experiments and an awesome GraphQL Playground for exploring your APIs.

Note

While most of GraphQL standard is already supported, Ariadne is currently missing support for the following features: unions, interfaces and inheritance, and subscriptions.

Requirements and installation

Ariadne requires Python 3.5 or 3.6 and can be installed from Pypi:

pip install ariadne
