Top 3 GraphQL code generators

There has been a lot of buzz in the web development world around GraphQL lately and for good reason!

GraphQL is a new query language for APIs and a server-side runtime for executing queries by using a type system you define for the data, so basically a syntax that describes how to ask for data and load it from a server to a client.

Why all the buzz?

The answer is simple:

It's all about the development speed.

The main reason why companies started using GraphQL is that it promises to speed up your API development, what's more, it manages to deliver!

In of the surveys directed to CTOs and lead developers of a variety of teams ranging from 1 to 100+ engineers (among which we can find tech giants like Uber or Paypal) about their perception of GraphQL implementation in their teams almost all companies felt GraphQL delivered on their expectations.

Let me introduce you three useful GrapphQL code generators to speed your development:

1. GraphQL Zeus

Zeus, son of Kronos, father of Apollo.

A simple tool working in Node.js & browser to generate an auto-complete client library for Javascript or Typescript. The unique thing about GraphQL Zeus is that it creates its own specification along with type-safe completion of request & responses.

How it works

GraphQL Zeus is the absolute best way to interact with your GraphQL endpoints in a type-safe way. Zeus uses your schema to generate Typescript types and strongly typed clients to unlock the power, efficiency, productivity and safety of Typescript on your GraphQL requests.


⚡️ Types mapped from your schema
⚡️ Works with Apollo Client, React Query, Stucco Subscriptions (*more coming soon...)
⚡️ Works with Subscriptions
⚡️ Infer complex response types
⚡️ Create reusable selection sets (like fragments) for use across multiple queries
⚡️ Supports GraphQL Unions, Interfaces, Aliases and Variables
⚡️ Handles massive schemas
⚡️ Supports Browsers, Node.js and React Native in Javascript and Typescript
⚡️ Schema downloader
⚡️ JSON schema generation

2. Prisma GraphQLGen

The tool from Prisma team provides a type-safe environment which helps maintain confidence about your code. As creators mention the motivation behind it was to

"(...) leverage the strongly typed GraphQL schema with the goal of making your backend type-safe while reducing the need to write boilerplate through code generation".

The graphqlgen generates & scaffolds type-safe resolvers based on your GraphQL Schema in TypeScript & Flow.

Deprecation note

graphqlgen has been officially deprecated in favor of the The Guild's project GraphQL Code Generator. Learn more about the collaboration of Prisma and the Guild in this blog post.



  • Schema-first Design in SDL to derive ideal types
  • Type-safety Resolvers with precise signatures including parent, args and return type
  • DX Precise resolver types puts your editor intellisense to work
  • Ecosystem Interop codegen suitable for Yoga 1 or Apollo Server and supports prettier and graphql-import out of the box


Programming in type-safe environments can contribute toward great confidence in your code's integrity. graphqlgen aims to leverage the GraphQL type system to make your resolvers completely…

3. GraphQL Code Generator

GraphQL Code Generator is a tool that generates code out of your GraphQL schema, supporting custom plugins & templates, so regardless of the language that you're using (i.e. TypeScript, React, Angular) GraphQL Code Generator will be a huge help.

npm version

GraphQL Code Generator is a tool that generates code out of your GraphQL schema. Whether you are developing a frontend or backend, you can utilize GraphQL Code Generator to generate output from your GraphQL Schema and GraphQL Documents (query/mutation/subscription/fragment).

By analyzing the schema and documents and parsing it, GraphQL Code Generator can output code at a wide variety of formats, based on pre-defined templates or based on custom user-defined ones. Regardless of the language that you're using, GraphQL Code Generator has you covered.

GraphQL Code Generator lets you choose the output that you need, based on plugins, which are very flexible and customizable. You can also write your plugins to generate custom outputs that match your needs.

You can try this tool live on your browser and see some useful examples. Check out GraphQL Code Generator Live Examples.

We currently support and maintain these plugins (TypeScript, Flow…

What about the Apollo for GraphQL? How well does it fare against the 3?

I'm afraid apollo doesn't generate the code for you. You would need codegen working with apollo.
