The Guild GraphQL

The Guild is the most influential open source organization in the GraphQL ecosystem, maintaining a comprehensive suite of production-grade tools that power API infrastructure for Microsoft, Uber, Klarna, KLM, Air France, Schneider Electric, Nordea, Bank Hapoalim, Rabobank, Pepper, The Graph, Outreach, Dalet, DFDS, and RedwoodJS. Founded by GraphQL pioneers Uri Goldshtein and Kamil Kisiela, the organization develops modular tools adoptable individually or as a unified platform across five categories. Schema Evolution includes Hive Console, an open source GraphQL Federation Platform with schema registry, gateway, analytics, and breaking change detection, alongside Inspector for schema governance. Gateway solutions include Hive Router, an MIT-licensed GraphQL Federation Router built in Rust for maximum performance with TLS and mTLS support, HTTP/2 with h2c for subgraph traffic, OpenTelemetry tracing, Prometheus metrics, and persisted documents with CDN storage and allowlist enforcement. Subgraph tools include GraphQL Mesh integrating any API type into a unified graph, GraphQL Yoga as a performant server, Envelop as the plugin system, SOFA for REST generation from GraphQL schemas, and GraphQL-Scalars for type-safe custom scalars. Developer Experience tools include GraphQL Codegen with over 40 million weekly downloads generating typed queries and resolvers across TypeScript, Flow, Java, Kotlin, Csharp, and Dart, plus GraphQL-ESLint for linting operations and schemas. The organization also maintains Nextra, the popular Next.js documentation framework. The blog is the most widely read publication in the GraphQL community. Professional services include consulting, team training, and engineering partnerships where Guild engineers work directly with client teams on architecture reviews and code quality.
