A new open-source utility called graphql-safe-guards offers a lightweight way to protect GraphQL APIs from expensive queries. It combines query depth limiting and query complexity validation into a single package, aiming to prevent resource exhaustion from overly nested or complex operations.

Unlike directive-based plugins or runtime middleware, this tool leverages native GraphQL validation rules. This approach makes it framework-agnostic, predictable, and introduces zero runtime overhead. It's designed for developers running GraphQL in production who need simple, portable safety measures without sacrificing performance.

For teams managing public or internal GraphQL endpoints, predictable query safety is a growing concern. This utility addresses common attack vectors like deep nesting or expensive field selections. Its release adds another option to the ecosystem of GraphQL security tools, focusing on simplicity and integration at the validation layer.
