Spec vs Traffic Drift Analyzer
Upload OpenAPI and HAR to identify undocumented endpoints, mismatched methods, and missing parameters between spec and real traffic. Free by Graph Tools.
Use this free spec vs traffic drift analyzer to compare your OpenAPI specification against real captured API traffic in a HAR file. The tool identifies paths called in traffic that are absent from the spec, method mismatches, parameter discrepancies, and schema drift between declared and observed request shapes. Upload both files and get a comprehensive drift report. Useful for API governance teams, security engineers, and developers validating that specs accurately reflect production behavior.
