Our verdict on graphql-lint

graphql-lint is an open-source Rust tool for developers who need checks on GraphQL SDL schemas. It comes in two forms: a library crate for use from Rust projects and gqlint, a command-line interface for linting. Its published rules cover naming conventions across schema types, fields, arguments, directives, enums, unions, and interfaces. The tool also requires a reason argument when a schema uses the @deprecated directive. This makes it a fit for Rust teams that want repeatable schema checks in a codebase or command-line workflow, rather than a general-purpose API definition linter.

The scope is deliberately specific: the listed checks focus on naming and deprecation, and the category specification identifies GraphQL schema linting rather than OpenAPI or AsyncAPI linting. Custom rules are not supported. Teams needing a tailored policy engine or checks spanning multiple API description formats should look for a broader tool. For projects whose requirements align with its published rules, the combination of a library crate and CLI provides two ways to bring the checks into a workflow without changing the product's narrow focus.

The project is open source and has a free plan, with Linux, macOS, and Windows listed as supported platforms. Deployment is self-hosted, which suits teams that want to run linting within their own development environment. Grafbase also documents a separate GraphQL schema linting workflow in its platform CLI, but that is distinct from graphql-lint/gqlint; buyers evaluating this product should assess the standalone Rust library and CLI on their own terms. Choose graphql-lint when GraphQL SDL naming and deprecation rules are the main need, especially in a Rust project. Choose another option when you need custom rules, broader API-format coverage, or a wider set of published lint checks.
