GraphQL Linter review
A focused GraphQL schema linter for pre-commit checks and CI pipelines.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
GraphQL Linter is a command-line tool from Schuberg Philis for checking GraphQL SDL schema files, including .graphql and .graphqls files. It fits teams that want schema-focused linting in their development workflow, from smaller groups to enterprise teams. The tool checks syntax and design-rule findings, and validates Apollo Federation directives. Its focus is deliberately narrower than general API description linting, so teams that need OpenAPI or AsyncAPI linting should look at alternatives.
The workflow is suited to repositories that already use pre-commit or CI: GraphQL Linter can run as a pre-commit hook or in a CI pipeline, including through GitHub Actions. It can lint files together by directory and return a non-zero exit code when it finds issues, which supports automated checks. Distributed as a standalone Go binary, it avoids requiring a Node.js toolchain; prebuilt binaries are available for Linux and macOS, and installation with Go is also supported. This makes it a practical fit where a small, command-line check is preferred over a broader linting platform.
Configuration settings and finding suppressions let teams tune the checks and silence selected findings. The project is open source, and its published distribution is self-hosted rather than a hosted service. It does not support user-defined custom lint rules, so teams seeking to encode their own rule sets may prefer a more extensible linter. Choose GraphQL Linter for focused schema checks and Federation validation in existing hooks or pipelines; skip it if your requirements span API description formats or depend on custom rules.
