Ariadne is a Python library for implementing GraphQL servers, inspired by Apollo Server and built with GraphQL-core.
Warning: The work on library is currently in experimental phase. We invite you to give Ariadne a try, but if you are looking to build production-ready GraphQL API, please use more stable solutions such as Graphene.
