GraphQL.js vs Hot Chocolate

GraphQL.js is the official JavaScript implementation of the GraphQL specification. It provides a parser, validator, executor, type system and related utilities for building GraphQL servers, clients, tools and schema workflows in JavaScript or TypeScript. Developers define a type schema and serve queries against it; the graphql function checks syntax and semantics before execution and reports invalid queries. Documentation identifies v17 as the current stable release, with v16 available for projects requiring older Node.js versions. Getting-started instructions require Node.js 22 or newer and provide installation commands for npm, pnpm, yarn and bun. The library runs in Node servers and browsers, distributes CommonJS and ESModule files, and the project says webpack and rollup builds should work. It is MIT-licensed, free, distributed through npm and intended for self-hosted deployment. Latest and previous major versions receive stated support, but no Long-Term Support version is offered.

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.
