10 Best GraphQL Tools Tools in 2026

Apollo Studio provides visibility into your GraphQL APIs. See which queries clients actually run, track performance by field and resolver, and catch schema changes that would break existing clients. The explorer lets developers browse and test queries against your schema interactively. Schema checks in CI prevent breaking changes from reaching production. Contract testing validates that client queries match server capabilities. Teams running GraphQL in production need observability. Apollo Studio provides the monitoring and governance that keep GraphQL APIs healthy as they evolve.

Gel is an integrated data platform built on top of PostgreSQL, designed to modernize the relational database experience. It provides a fresh approach to data modeling with object types and links instead of traditional JOINs, simplifying complex queries and migrations. Gel offers a complete database workflow from local development to cloud deployment with zero-config setup, built-in tooling, and robust client libraries for various programming languages. Gel is targeted at developers looking for a more intuitive and efficient way to interact with Postgres, especially those working with modern application stacks. It addresses common database challenges like N+1 problems, complex migrations, and schema management. Key benefits include end-to-end type safety, integrated authentication, AI/GenAI readiness with vector stores and RAG endpoints, and high performance due to query composability and optimized network interactions. The platform is fully open source and provides features like graph queries, a high-level schema engine, and client SDKs for Python, TypeScript, Go, Dart, Rust, .NET, and Java. It also includes tools for local development, cloud deployment with encryption and backups, and integrations with platforms like Vercel and GitHub.

Hygraph (formerly GraphCMS) is a headless CMS that pioneered GraphQL-first content APIs. The platform focuses on content federation - connecting and unifying content from multiple sources. Hygraph is known for its powerful GraphQL API, content localization, and flexible content modeling. The platform is popular among teams building complex content architectures that need to combine content from different systems into a unified API.

KeystoneJS builds Node.js backends with an auto-generated admin UI. Define your schema, get APIs and a content management interface—backend development accelerated. The admin UI is automatic. The API is GraphQL. The customization is full. Node.js developers wanting rapid backend development choose KeystoneJS for schema-driven development.

Dgraph stores and queries graph data with native GraphQL support. Model relationships naturally, query them efficiently—a distributed graph database that speaks GraphQL natively. The query language is GraphQL. Horizontal scaling distributes data. The focus is making graphs accessible, not just possible. Applications modeling highly connected data choose Dgraph for graph storage that integrates naturally with modern development.

FaunaDB is a serverless database designed for modern applications. Global distribution, strong consistency, and a document model with relational capabilities—database that scales without ops. The query language is powerful. Global replication is automatic. The serverless model eliminates capacity planning. Developers wanting a database that handles scale without database administration choose Fauna for serverless global data.

Apollo GraphQL provides tools and cloud services for building and managing GraphQL APIs. Apollo Client is the most popular GraphQL client for frontend apps. Apollo Server builds production-ready GraphQL servers. Apollo Federation composes multiple services into one graph. Apollo Studio provides schema management, monitoring, and observability. The complete platform for GraphQL at any scale.

Apollo GraphQL provides the definitive platform for building with GraphQL. Client libraries for web and mobile handle caching, state management, and query batching. Server tools make building GraphQL APIs straightforward. Apollo Studio adds observability—see how clients use your schema, track performance, and catch breaking changes before deployment. Federation lets multiple teams contribute to a unified API without coordinating deployments. Teams adopting GraphQL usually end up with Apollo because it solves the entire problem, from client to server to operations.

GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling those queries with your existing data. It allows clients to request exactly the data they need, eliminating over-fetching and under-fetching common in traditional REST APIs. This leads to more efficient and performant applications by reducing network requests and ensuring predictable responses. Designed for developers building modern applications, GraphQL provides a type-safe schema that defines the shape of your data, ensuring consistency, self-documentation, and clear error handling. It supports evolving APIs without versioning by allowing new fields and types to be added seamlessly. GraphQL is storage-agnostic, meaning it can integrate with various data sources like databases, REST APIs, and third-party services, creating a single, cohesive data layer. It is supported by a strong community and offers powerful tools for development, including introspection and code intelligence. The GraphQL Foundation, hosted by The Linux Foundation, provides a neutral home for the GraphQL trademark and supports the continued evolution of the specification and reference implementations through funding, mentorship, and collaboration infrastructure. This ensures the sustainability and growth of the GraphQL ecosystem.

Altair GraphQL Client is a powerful tool designed to simplify the process of interacting with GraphQL APIs. It provides a comprehensive environment for developers to write, test, and manage their GraphQL queries, mutations, and subscriptions. The client offers features like schema documentation browsing, query auto-completion, and the ability to switch between different environments (local, staging, production). This tool is ideal for individual developers and teams working with GraphQL. It streamlines the development workflow by enabling easy saving and sharing of queries, pre-request and post-request scripting for dynamic operations, and support for various authentication methods. Altair GraphQL Client aims to enhance productivity and collaboration by offering a robust platform for all GraphQL API interactions, from initial testing to ongoing maintenance. Key benefits include faster query development through intelligent editors, improved collaboration via query collections and sharing, and enhanced testing capabilities with environment management and script execution.
