Our verdict on graphql-schema-linter

graphql-schema-linter is a command-line tool for validating GraphQL schema definitions against configurable rules. It suits developers and teams that want to enforce schema conventions in their development workflow, including through pre-commit hooks. The project is open source and distributed as an npm package, with Linux, macOS, and Windows listed as supported platforms. Its narrow focus makes it relevant to GraphQL teams rather than organizations seeking a general API linting suite.

Rule selection and customization are central to the tool. Users can choose rules through command-line options, adjust rule settings, and load custom rules from specified paths. It can also ignore selected errors for schema members, which gives teams a way to handle exceptions without abandoning the rest of their checks. Configuration can live in package.json or a dedicated configuration file. Schema definitions can be read from standard input, and results are available in text, compact, or JSON formats. These options support a configurable workflow, though teams should expect to work with a CLI rather than a listed graphical interface or integration catalog.

The project is community-maintained, and community is the listed support channel. It is self-hosted and open source, with no paid tiers described here; prospective adopters should account for managing its use within their own development process. The listed scope excludes OpenAPI and AsyncAPI linting, so teams working across those specifications may prefer a broader tool. Choose graphql-schema-linter when configurable GraphQL rules, custom rule loading, and lightweight command-line use are the priority; look elsewhere if you need broader API specification coverage or a listed integration ecosystem.
