Can Diff Anything detect breaking OpenAPI changes?
Diff Anything compares OpenAPI and JSON Schema with API compatibility in mind rather than reporting only textual movement. Pro batch manifests can emit JSON, JUnit, or SARIF to stdout and return process exit codes for release checks.
Do compared files leave the computer?
No. Comparison is local. The application has no account, cloud comparison service, analytics, or telemetry.
How does automatic mode choose a comparison?
Matching structured formats use their semantic engine, two folders use folder comparison, and other compatible inputs fall back to text. You can always choose a concrete mode.
Go deeper
Run repeatable comparisons, read highlighted terminal output, interpret exit codes, integrate with Git, and publish machine-readable CI results.
