+## GraphQL Java
 [graphql-java](https://graphql-java.com/) is one of the most popular JVM based GraphQL implemenations. GraphQL Kotlin is
 built on top of `grahpql-java` as it can be easily extended with additional functionality and this implementation
 has been used and tested by many users.

 This makes changes in code directly reflect to your schema and you can still produce the `GraphQLSchema` to print and export an SDL file.

+
+## DGS
+[DGS](https://netflix.github.io/dgs/) is a GraphQL server framework for Spring Boot. It works with both Java and Kotlin.
+DGS is also built on top of `graphql-java` and implements many similar features to `graphql-kotlin` and [graphql-java-kickstart/graphql-spring-boot](https://github.com/graphql-java-kickstart/graphql-spring-boot).
+
+* Auto-configuration of server routes and request handling
+* Auto-wiring of data fetchers (resolvers) to the `GraphQLSchema`
+* Apollo Federation support
+* Subscriptions support
+* Client schema-code generation
+
+While both libraries do very similar things, there are some minor differences which may serve different usecases better.
+As with open source library, you can compare and use the right tool for the job.
+
+### Extra Features of DGS
+
+* Support for a SDL-First (Schema-First) approach
+* Ability to autogenerate code stubs from the schema
+* Includes [JsonPath](https://github.com/json-path/JsonPath) testing library
+* Build on top of Spring MVC
+
+### Extra Features of graphql-kotlin
+
+* Supports code-first approach (generates schema from source code - does not require duplicate implementation of data fetchers, schema classes, and SDL files)
+* Abstract server logic can be used in any framework, e.g. Ktor
+* Reference server implementation build on top of [Spring Webflux]((https://spring.io/reactive) for a reactive server stack
+* Simple nesting of data fetchers
+* Client code generation for Ktor and Spring
+* Client plugin support for both Maven and Gradle
