Graphene vs PostGraphile: What are the differences?

Developers describe Graphene as "GraphQL framework for Python". Graphene is a Python library for building GraphQL schemas/types fast and easily. On the other hand, PostGraphile is detailed as "Instant GraphQL API for your PostgreSQL database; use standalone or as a Node.js middleware; MIT-licensed OSS". Execute one command (or mount one Node.js middleware) and get an instant high-performance GraphQL API for your PostgreSQL database.

Graphene and PostGraphile can be categorized as "Query Languages" tools.

Some of the features offered by Graphene are:

• Easy to use: Graphene helps you use GraphQL in Python without effort.
• Relay: Graphene has builtin support for Relay
• Django: Automatic Django model mapping to Graphene Types. Check a fully working Django implementation

On the other hand, PostGraphile provides the following key features:

• instant GraphQL schema via reflection over PostgreSQL database API
• compiles complex GraphQL queries into very few SQL statements resulting in high performance
• built entirely from plugins - heavily customisable

Graphene and PostGraphile are both open source tools. PostGraphile with 7.49K GitHub stars and 364 forks on GitHub appears to be more popular than Graphene with 4.71K GitHub stars and 502 GitHub forks.
