Hot Chocolate vs Netflix DGS

Hot Chocolate is an open-source GraphQL server for.NET that runs on ASP.NET Core and builds a GraphQL schema from C# types and resolvers. Developers can define typed schemas through implementation-first or code-first methods. It supports GraphQL over HTTP and WebSocket, plus Server-Sent Events for streaming responses. Documentation describes schema downloads, a Nitro GraphQL IDE endpoint, and a command-line interface for schema export. Data integrations include Entity Framework, MongoDB, and Marten; DataLoaders and batch resolvers help batch and cache related requests. OpenTelemetry instrumentation covers server, execution, and DataLoader activity. Security guidance recommends query cost analysis, pagination and execution-depth limits, and timeouts for public APIs; trusted documents can restrict private APIs to registered operations. Servers can act as Fusion subgraphs. Hot Chocolate implements the GraphQL 2025 specification and GraphQL over HTTP, and supports spec-compliant clients including Strawberry Shake, Relay, and Apollo Client. It is MIT licensed for commercial or private use. Community support is free; paid Startup support starts at $450 per month and includes two critical incidents.

Netflix DGS is a free, open-source GraphQL server framework for Spring Boot, deployed as a self-hosted API service. Its annotation-based programming model supports Java and Kotlin, with Gradle or Maven builds. DGS favors schema-first development: schema files belong in src/main/resources/schema, and its Gradle plugin can generate Java types from a GraphQL schema. A test framework runs GraphQL queries in lightweight unit tests, while data loaders batch requests to help address the N+1 problem. The framework supports GraphQL Federation, WebSocket and SSE subscriptions, file uploads, error handling, and extension points. Spring Security integration allows @Secured on data fetchers after security configuration. DGS also integrates with Spring for GraphQL, although that path currently lacks SSE subscriptions and some DGS data-loader features do not work with Spring for GraphQL data loaders. A browser GraphiQL editor and an IntelliJ plugin are included. Current documentation requires Spring Boot 3 and JDK 17; DGS 11+ with Spring Boot 4 is actively maintained, while DGS 10.x receives most feature backports until the second half of 2026.
