JSON Schema Diff & Compatibility Checker
Compare two JSON Schemas and classify breaking vs non-breaking changes with path-aware diff reporting and a compatibility verdict. Free by Graph Tools.
Use this free JSON Schema diff and compatibility checker to compare two versions of a JSON Schema and receive a classified change report. Breaking changes — removed required properties, narrowed types, added required fields, tightened constraints — are distinguished from safe non-breaking additions. Results include a compatibility verdict and a path-aware diff. Useful for API developers managing schema evolution, library authors publishing versioned schemas, and QA engineers validating schema changes.
