API Dependency Mapper
Infer operation, schema, and authentication dependencies from an OpenAPI spec to inform architecture reviews. Free by Graph Tools.
Use this free API dependency mapper to infer operation, schema, and authentication dependencies from an OpenAPI specification. Paste your spec and get a structured dependency graph showing which operations share schemas, which depend on the same security schemes, and which request/response types are reused across paths. Useful for architects planning refactoring, developers understanding API coupling before changes, and teams assessing the blast radius of a schema modification.
