    What makes this tool different

    Unlike other OpenAPI linters, @redocly/cli defines the possible type tree of a valid OpenAPI definition and then traverses it. This approach is very similar to how linters for programming languages work and results in major performance benefits over other approaches. Extend functionality at different points in the lifecycle with preprocessors, rules, and decorators.

    Thanks to graphql-js and eslint for inspiration of the definition traversal approach and to Swagger, Spectral, and OAS-Kit for inspiring the ruleset.
